01 — Core Mechanism

The SBRA System

Score-Based Reward Allocation is the engine behind AFN. It translates verifiable work into proportional token ownership — transparently, on-chain, with no discretionary overrides.

SBRA operates on a simple principle: track what people build, then mint tokens proportionally. Every contribution is logged against a defined scoring rubric. At the end of each sprint cycle, scores are tallied, a multi-sig governance vote approves the allocation, and the SDM token contract mints accordingly. No subjective bonuses. No founder discretion. The score is the record.

⚙️
Why on-chain? Because any off-chain tracking system — spreadsheets, HR tools, verbal agreements — can be altered or disputed. Logging contribution scores to Polygon PoS creates an immutable audit trail. Every contributor can independently verify their score history and the token allocation it produced. The chain is the source of truth.

What the scores mean

These percentages represent category completion relative to current sprint targets — not arbitrary grades.

Engineering at 78% means 78% of planned engineering deliverables for the current sprint have been verified as complete.

Tokens are allocated at sprint close proportionally to each contributor's share of total verified points across all categories.

SBRA scores contributions across three primary dimensions. Each has defined point values so contributors always know exactly what their work is worth before they do it.

How allocation is calculated

At the close of each sprint, individual scores are summed and expressed as a percentage of total platform points earned that sprint.

// Contributor allocation formula
contributor_share = your_points / total_points_all_contributors
sdm_earned = sprint_pool × contributor_share

"Verified" has a specific meaning in SBRA. Contributions aren't self-reported — they go through a defined review process before any score is recorded.

🔐
Multi-sig approval required. No single party — including founders — can unilaterally approve or modify a contribution score. The Gnosis Safe multi-sig wallet requires a threshold of authorized signers to approve each sprint's allocation before the SDM mint is triggered.

Work Completed

A contributor completes a trackable deliverable — a PR, a design file, a documentation update, a deployment task. The work is tangible and verifiable by a peer, not self-declared.

AFN's token infrastructure is built on Polygon PoS. The SDM token is an ERC-20 with controlled minting — only the Gnosis Safe multi-sig can trigger new mints. There are no admin keys or backdoors.

// SDM Token — simplified core interface (ERC-20 + controlled mint) contract SDMToken is ERC20, Ownable { // Only the Gnosis Safe multi-sig address can call mint() address public governanceMultisig; modifier onlyGovernance() { require(msg.sender == governanceMultisig, "Not authorized"); _; } // Called once per sprint — after multi-sig approval of SBRA scores function mintAllocation( address[] calldata contributors, uint256[] calldata amounts ) external onlyGovernance { for (uint i = 0; i < contributors.length; i++) { _mint(contributors[i], amounts[i]); } } }
🔍
All minting events are publicly verifiable on Polygonscan. Every token allocation to every contributor is a logged transaction on-chain. No allocation can happen silently — it's a public record from the moment it's executed.

Why Polygon PoS?

⚡ Gas costs
Sprint allocations involve minting tokens to multiple addresses in a single transaction. On Ethereum mainnet this would be prohibitively expensive. On Polygon PoS, the same transaction costs fractions of a cent.
🏦 Gnosis Safe support
Gnosis Safe is battle-tested on Polygon with a rich ecosystem of tooling. Multi-sig governance via Safe gives AFN a transparent, auditable approval flow without building custom governance infrastructure.
🌐 EVM compatibility
Full EVM compatibility means standard Solidity contracts, Hardhat/Foundry tooling, and eventual bridging to Ethereum mainnet or any EVM-compatible chain if needed — no vendor lock-in.
💧 DEX liquidity path
Polygon has mature DEX infrastructure (QuickSwap, Uniswap v3). When vesting periods complete and contributors want liquidity, the SDM token can be listed without bridging overhead.

Two paths to ownership.

AFN has two contributor tiers with different access levels, token allocations, and vesting schedules. Both earn real SDM tokens. The difference is commitment level and timing.

Tier 1
Core Contributor
Full-time or near-full-time commitment to AFN's core roadmap. Core contributors are onboarded in the founding phase and have the highest earning potential within the SBRA system.
Access to 35% core contributor token pool (350M SDM)
Higher point multipliers on strategic deliverables
Governance voting rights from day one
2-year vesting with 6-month cliff
Invited by existing core contributors or founders
Tier 2
Future Contributor
Part-time or project-based contributors who join after the founding phase. Future contributors earn from the community pool and can transition to Core Contributor status with sustained contribution.
Access to 8% future contributor pool (80M SDM)
Standard SBRA scoring, no multipliers
Governance rights after 90-day probation period
2-year linear vesting, no cliff

This estimator uses fixed point values and a modeled platform activity baseline. Actual SDM earnings depend on total contributions across all active contributors in a given sprint. Not a financial guarantee.


Vesting schedules, in full.

Every stakeholder group has a defined vesting schedule. These are enforced programmatically — not contractually. The smart contract won't release tokens before the schedule permits.

Full vesting (Founders)
Founders
4yr / 1yr cliff
Nothing unlocks until month 12. Then linear monthly release over 36 more months. Double-trigger acceleration on exit events.
Core Contributors
2yr / 6mo cliff
No tokens until month 6. Then linear monthly release over 18 months. SBRA points accrue from day one regardless of vesting status.
Future Contributors
2yr linear
No cliff. Tokens vest linearly from month 1, in proportion to ongoing SBRA scores. Incentivizes continuous contribution over time.

05 — Why AFN

AFN vs the alternatives.

How AFN's model compares to traditional equity, vague web3 promises, and open-source with no ownership path.

Feature AFN (SBRA) Traditional Equity Vague Web3 "Tokens" Open Source (No Ownership)
Ownership based on actual work On-chain, scored ~ Discretionary ~ Often pre-mined None
Verifiable and auditable Polygonscan public Cap table is private ~ Chain txs visible, logic unclear N/A
No founder override on allocations Multi-sig required Board/founder discretion Usually single admin key N/A
Governance rights for contributors Voting via Safe Rarely before Series A ~ Token-weighted voting None
Liquidity path exists DEX on Polygon IPO/acquisition only ~ Depends on project None
Works for non-engineers Design + ops scored ~ Sometimes Mostly dev-centric ~ Contributions welcome, no reward
Transparent scoring rubric Published point values Opaque performance reviews Usually undefined N/A

07 — Technical FAQ

Questions developers ask.

The questions that matter — answered directly, without spin.

What stops the founders from gaming the SBRA scores?
Three things. First, the scoring rubric is published — if a founder submits a PR that earns 25 points but a contributor's equivalent PR gets fewer, that discrepancy is visible to the whole team. Second, the Gnosis Safe multi-sig requires multiple signers to approve each sprint allocation — a founder can't unilaterally push through a self-serving allocation. Third, all minting transactions are publicly visible on Polygonscan. Any irregular allocation pattern would be immediately apparent to any contributor who checks the chain. The honest answer is: we're early stage and trust is still partly social. The on-chain infrastructure makes cheating much harder and much more visible than in any traditional equity arrangement.
Is the SDM token contract deployed yet? What's the address?
The SDM token contract is currently in final audit and testnet validation on Polygon Mumbai. Mainnet deployment is targeted for the close of the founding sprint cycle. The contract address will be published here and on our GitHub the moment it's deployed. We will not ask contributors to interact with any contract before that announcement — be wary of any unofficial claims of an early SDM contract address. The only source of truth is this site and the official AFN GitHub repository.
What happens to my accrued SBRA points if I stop contributing?
Points already converted to SDM tokens at sprint close remain yours — they're in your wallet and governed by the vesting schedule, but they can't be taken back. If you stop contributing mid-sprint, work completed and verified before the sprint close still earns that sprint's allocation. Work in progress that isn't verified at sprint close doesn't score. Unvested tokens follow the vesting schedule regardless — stopping contribution doesn't accelerate vesting, but it also doesn't forfeit already-earned tokens. There is one exception: if a Core Contributor is removed for cause (defined in the governance charter), the Safe multi-sig can vote to pause future vesting. Already-vested tokens are never clawed back.
How is "verified" defined for non-code contributions?
Engineering contributions have clear verification signals (merged PRs, deployed code, closed issues). For design and operations, verification is peer-based: a deliverable is considered verified when a second contributor — not the one who produced it — marks it complete in Taiga, attaches the output artifact (design file, doc, deployment log), and a sprint lead confirms it meets the sprint definition of done. This isn't perfect — peer review for non-code work has subjectivity. We document edge cases in the SBRA scoring guide and evolve the rubric each quarter based on team feedback. The scoring guide is public on GitHub. If you disagree with a point value, that's a governance proposal.
Can SDM tokens be traded before the platform launches?
Vested SDM tokens are standard ERC-20 tokens on Polygon — technically, nothing stops peer-to-peer transfers once vested. However, there is no liquidity pool and no official DEX listing until platform launch milestones are met. Trading in that environment means finding a willing counterparty yourself, with no price discovery mechanism and high information asymmetry. We recommend against it. The token's value proposition is tied to AFN platform utility and governance rights. Pre-launch trading undermines that by creating a speculative dynamic that doesn't reflect the platform's actual progress. The plan is to establish a QuickSwap or Uniswap v3 pool on Polygon at a defined platform milestone, with treasury funds seeding initial liquidity.
What's the minimum viable contribution to join?
For Future Contributors, there's no minimum — you can contribute as much or as little as you have capacity for, and earn proportionally. That said, very low contribution levels (under ~20 SBRA points per sprint) produce negligible token allocations and are difficult to verify consistently. Realistically, a part-time contributor putting in 5–8 hours per week can generate meaningful SBRA scores. For Core Contributor consideration, the expectation is sustained, substantial contribution across at least two sprint cycles — enough to establish a verifiable track record before the expanded allocation and governance rights are extended.
