Status: Phase 0 - Scoping document

• Informational document - not financial or legal advice.
• Some capabilities depend on ERC-4337, paymasters and L2 usage.
• Reference amounts are in crypto units. Fiat equivalents are only indicative.
• Transparency required: commission (published degressive schedule), aggregation windows, supported networks, chosen gas option and campaign cap must be publicly displayed.
• Campaign cap: gas + commission + technical reserve ≤ public threshold (e.g., 15%).

We reason in crypto, not in fiat.
Amounts are counted in native units of the chosen chain. Example: you donate 0.0100 ETH, the NGO receives 0.0090 ETH if the announced commission is 10%. This logic neutralizes volatility in the split. The fiat value remains fluctuating until each party converts.
Euro equivalents exist only for readability.

• L2-first: operations prioritized on low-fee L2s (e.g., Optimism, Arbitrum) so gas is marginal.
• Conditional execution: execute only when the donation-to-fee ratio turns green.
• Relayer gas pool: relayer maintains a pool of the native gas token (e.g., ETH on L2 EVM). No conversion is taken from donations to fund the commission.
• Optional safety net: if the gas pool is insufficient, a minimal, on-chain documented conversion may buy the gas token without changing the split formula.
• Standard display:
  • Formula:

    NGO net = Aggregated amount - reimbursed gas - relayer commission - technical reserve

  • Commission displayed as % of donated crypto (e.g., 7% in ETH if donation in ETH)
• Transparency: the chosen gas option (pool, L2-first, safety net) and the campaign cap (e.g., 15%) are publicly declared by each relayer.

• On Ethereum L1, gas is paid in ETH and can exceed small donations. On L2 it is much lower but never zero.
• Several EVM L2s also use ETH as gas token (e.g., Arbitrum, Optimism). Polygon PoS uses POL after MATIC→POL migration.
• Consequence: an isolated micro-donation is often inefficient on L1, sometimes acceptable on L2, and depends on network conditions.

Aggregation + on-chain transparency + split in crypto units:

• Relayers aggregate micro-donations during a limited period, then perform one grouped transfer to the NGO.
• Split in crypto units, with gas reimbursed first and published degressive commission.
• Publication of a campaign cap: gas + commission + technical reserve ≤ public threshold (e.g., 15%).
• NGO share and commission are expressed as a percentage of donated crypto, not as a fiat equivalent.
• Traceability via public explorers (e.g., Etherscan).

Existing technical bricks:

• Account Abstraction ERC-4337 with paymasters for donor-side gas sponsoring.
• EIP-2612 permit where available, approving by signature without an on-chain approve.

Step 1 - Donation

• AA smart account with paymaster: gas sponsored, donor does not pay directly.
• EOA + token with permit: gasless approval, then relayed donation.
• EOA + token without permit: a paid approval may be required depending on the token.

Step 2 - Aggregation

• Donations collected in an aggregation contract. Triggers: amount threshold, max time window, acceptable gas window.

Step 3 - Grouped transfer

• A single transaction ships funds to the NGO.
• Standard formula:

  • NGO net = Aggregated amount - reimbursed gas - relayer commission - technical reserve

Step 4 - Public reporting

• Donations, any conversions and the final transfer are visible on the chain explorer.

Physical constraints: on EVM, gas is paid in the native token of the chain. Examples: ETH on Ethereum, Optimism, Arbitrum. POL on Polygon PoS.
To respect “no conversion for the commission”, DustEthic v0.2 proposes explicit options to fund gas:

• Option A - Relayer gas pool: no conversion from donations.
• Option B - Minimal documented conversion: pro-rata in-kind skim to buy gas token, logged on-chain, without affecting the split beyond gas cost.
• Option C - L2-first: prioritize low-fee L2s so gas is marginal.
• Option D - Sponsors: paymasters funded by partners, reimbursed periodically.

Rule: the split is performed in crypto units. Percentages remain constant; the euro value varies until the NGO and relayer convert.
Stablecoins: reduce volatility but do not eliminate risk (depeg, freezes, issuer risk).
Post-receipt strategies:

• NGO: sell immediately, sell partially, or hold.
• Relayer: periodic selling, holding, or mixed approach.

• Donors: send small amounts, ideally via AA.
• Relayers: operate aggregation, publish public parameters, comply with v0.1 and keep signed logs of sensitive operations (with on-chain links).
• NGOs: receive directly into their wallet, set a conversion policy and minimal compliance procedures.

1. Choose a DustEthic-compliant relayer.
2. Connect your wallet.
3. Select the NGO.
4. Enter the amount in crypto.
5. Sign (AA/permit if possible, otherwise paid approve depending on token).

Cost for the donor: ideally zero via AA or permit. Otherwise, only the initial approval if required. Final transfer gas is mutualized and deducted before NGO payout.
Tracking: each donation and the final transfer are visible on the chain explorer.

• Recommended wallet: Safe multi-signature.
• Fiat conversion: via a registered exchange.
• Accounting: record upon receipt, define conversion policy, track addresses.
• Minimal compliance: address screening and a written policy. References: OFAC, FATF R.15 / Travel Rule.

Transparency

• Open-source code. Public parameters: degressive commission (suggested max 15%), campaign cap, aggregation windows, supported networks, chosen gas option.
• Signed logs and on-chain links; CSV export.
• Readable on-chain dashboard.

Non-custodial

• Funds held by smart contracts. No unilateral withdrawal.

Technical governance

• Admin under Safe multi-sig, timelock on critical changes, emergency procedures.

Security

• Independent audit before mainnet. Bug bounty after launch.

Gas and conversions

• Explicitly choose Option A, B, C or D and display publicly.
• Execute only if donation-to-fee ratio is favorable; gas reimbursed first.
• Commission always as % of donated crypto (published degressive schedule).
• If a gas conversion is necessary, log it on-chain.

AA and compatibility

• ERC-4337 + paymaster recommended on L2. Fallback EIP-2771 if 4337/7702 (AA) not supported.

Asset allowlist v1

• Ethereum and EVM L2s: ETH, USDC, USDT.
• Polygon PoS: possible but gas in POL - plan the logistics.
• Reject by default illiquid, taxed, honeypot or no-permit tokens if UX impractical.

Minimal compliance

• Proportionate AML policy, basic screening, logging of refusals.

• Every.org: USD conversion, 1% broker + network. Link
• The Giving Block: packages + processing fees. Link
• DustEthic: micro-donations via aggregation, native crypto split on L2, with published campaign cap and degressive commission.

Phase 0 - Foundations [Q4 2025]

• Standard v0.1 specification
• Asset/network allowlist v1
• Aggregation + paymaster contracts design - testnet
• Security and governance policy

Phase 1 - Development [2026]

• Open-source reference implementation
• Tests on Sepolia + L2s
• Third-party audit
• Pilots with 1 relayer and 2 NGOs

Phase 2 - Launch [2026+]

• Mainnet + 2 L2s

• Broader governance if traction

• Developers: smart accounts, paymasters, aggregators. ERC-4337 + EntryPoint refs.
• NGOs: test with Safe and an internal conversion policy.
• Relayers: L2-first implementation, publish gas metrics and delays.
• Community: feedback, translations, content.
