Contract Template Catalog

This page summarizes SatoshiNet smart contract templates, runtimes, and testnet entries. For more detailed protocol rules, see Smart Contract Protocol.

Current Status Matrix

Type	Status	Testnet Entry	Notes
Agent / Prediction Contract	Implemented / Testing	Prediction Contract Test	First public testnet validation scenario
Template Contract: AMM	Implemented / Testnet Iterating	PWA Tools -> Smart Contracts, Deploy AMM Pool	Smart contract template test capability, not market AMM
Template Contract: LimitOrder	Implemented / Testnet Iterating	PWA Tools -> Smart Contracts, Deploy Limit Order Module	Smart contract template test capability, not market limit order
Template Contract: Asset Exchange	Implemented / Testnet Iterating	To be added	Fixed-rule asset exchange scenario
Template Contract: Autopay	Implemented / Testnet Iterating	To be added	autopay.tc, pays a fixed or linear fee to one configured recipient by block height
EVM Runtime	Implemented / Testnet Iterating	EVM Developer Preview	Reuses Solidity / EVM ecosystem; invocation uses ABI calldata, and asset settlement still follows SatoshiNet UTXO model
EVM Sample: ConstantProductAMM	Implemented / Testing	PWA Tools -> Smart Contracts, EVM Sample Contracts	Solidity AMM standard sample, not market AMM
EVM Sample: LimitOrderBook	Implemented / Testing	PWA Tools -> Smart Contracts, EVM Sample Contracts	Solidity limit order standard sample, not market limit order

Template Documents Should Include

Each template contract should eventually include:

1. Contract type and template name.

2. Deployment parameters.

3. Invocation interfaces.

4. Input asset rules.

5. Result TX output rules.

6. Permission boundary.

7. Fees and GAS.

8. Explorer / Indexer verification method.

9. Testnet contract address or example txid.

10. Known limitations.

Current Priorities

1. Prediction contract: complete user testing, deployer quickstart, and testnet evidence.

2. AMM template contract: complete deployment, swap, add liquidity, remove liquidity, and verification flow.

3. LimitOrder template contract: complete order creation, filling, cancellation, and Result TX verification flow.

4. Autopay template contract: complete deployment, funding, per-block payment, close, and Result TX verification flow.

5. EVM sample contracts: add testnet addresses, txids, calldata generation records, and Explorer evidence for ConstantProductAMM and LimitOrderBook.

6. EVM Runtime: add RPC, Chain ID, example repo, Solidity deployment flow, estimate flow, and ABI calldata invocation flow.
