Token classes
4.1 On-chain assets and accounting metrics
Yumo Yumo separates two on-chain assets, one off-chain economic accounting unit, and one background contribution metric. INT and the proof-of-expense SBT are on-chain assets. bINT is the visible off-chain economic right used for Epoch 9+ settlement. cPoints records contribution volume and quality for background analysis and future airdrop work; it is not an Epoch 9+ bINT reward input. Hidden-cost insight is computed and shown per verified receipt as an analytics result.
| Class | Form | Transfer model | Role |
|---|---|---|---|
| INT | SPL token on Solana | Market-transferable | Protocol-level coordination, staking, ecosystem incentives. Supply parameters live in the Vision Paper. |
| bINT | Off-chain accounting unit (operations layer) | Settles to INT through a defined lifecycle | Contribution accounting layer between work and reward. |
| cPoints | Off-chain background metric | No settlement role in Epoch 9+ | Contribution volume and quality signal for analysis and future airdrop work. |
| Proof-of-expense SBT | Token-2022 non-transferable asset | Non-transferable | Marks a wallet as a verified expense contributor, minted once per account. |
Why the separation
The Vision Paper explains the user-experience reason. The mechanism reason is separation of concerns:
- INT moves through markets and exchanges; it is transferable and fungible.
- bINT is written as a locked economic right and settles to INT at a fixed 1:1 ratio after an eligible epoch is released; it is an off-chain unit, so accounting can evolve without per-event on-chain transactions.
- cPoints remains a separate background metric. Its rows can continue to support contribution analysis without changing Epoch 9+ bINT settlement.
- The proof-of-expense SBT carries contributor identity as a non-transferable Token-2022 asset, one per wallet.
4.2 Authority structure
Authority differs by whether a class is on-chain or off-chain.
- INT mint authority — held only until the full supply is minted at genesis, then closed. After genesis no INT can be minted; distribution is a treasury transfer through the audited distributor (4.15).
- INT treasury and burn — held by the Squads multisig, with separated approvals for distribution-root signing, treasury movement, and reserve clawback.
- bINT — off-chain accounting unit in the operations layer. It has no on-chain mint or freeze authority; its locked balances settle to INT through the Epoch 9+ lifecycle in 4.4 after the applicable release gates.
- Proof-of-expense SBT — Token-2022 with the non-transferable extension, minted by the backend one time per wallet. Non-transferability is enforced at the token-program layer.
Keeping bINT off-chain removes per-event on-chain authority from the contribution path; the only INT-level authority that persists after genesis is the multisig over treasury, distribution roots, and burns.
