SourceMint (SRCMNT)

Contribution, minted. SourceMint is an experiment in accounting for open-source contribution on-chain: a fixed-supply ERC-20 on Base with no ICO and no token sale. Supply enters circulation as rewards for merged contributions (reward policy); once distributed, the token trades freely like any ERC-20. The accounting invariant is enforced by code: every transfer out of a project wallet — rewards and any treasury liquidity provision alike — must be recorded in rewards/ledger.json with a reason, and CI verifies the ledger against the chain — an unaccounted movement fails the build in public.
