Onchain Integration
SignalArc currently references an Arc Testnet SignalArcMarket deployment and includes frontend browser-wallet transaction wiring in the current working tree. This is prototype/testnet behavior only.
Network
| Field | Value |
|---|
| Network | Arc Testnet |
| Chain ID | 5042002 |
| RPC URL | https://rpc.testnet.arc.network |
| Explorer | https://testnet.arcscan.app |
| Arc Testnet USDC ERC20 interface | 0x3600000000000000000000000000000000000000 |
Deployed Contracts
| Contract | Address | Status |
|---|
SignalArcMarket | 0xf4ccc11A9e24fb996679F946C23C04AFd2797F26 | Arc Testnet prototype reference. |
Contract Functions
Verified from contracts/src/SignalArcMarket.sol and contract tests:
| Function | Type | Notes |
|---|
isOpen() | View | Returns whether status is open and close timestamp has not passed. |
openPosition(Outcome side,uint256 amount) | Write | Transfers collateral from caller and records YES/NO position. |
claimableAmount(address user) | View | Returns claimable payout or refund amount. |
claim() | Write | Claims payout after resolution or refund after cancellation. |
closeMarket() | Write | Closes after close timestamp. |
cancelMarket() | Write | Resolver-only cancellation. |
resolve(Outcome winningOutcome_) | Write | Resolver-only resolution after close. |
question, closeTimestamp, resolver, collateralToken, status, winningOutcome, yesPositions, noPositions, hasClaimed, totalYes, totalNo, and totalCollateral.
Frontend-Used Functions
The current frontend uses:
| Contract | Function |
|---|
| Arc Testnet USDC ERC20 interface | approve(address,uint256) |
SignalArcMarket | isOpen() |
SignalArcMarket | openPosition(uint8,uint256) |
Outcome Mapping
The contract enum is:
| Solidity enum | Numeric value |
|---|
Outcome.None | 0 |
Outcome.Yes | 1 |
Outcome.No | 2 |
| UI outcome | Contract value |
|---|
| YES | 1 |
| NO | 2 |
USDC Decimals
The project state records Arc Testnet USDC ERC20 interface behavior as 6 decimals. The test-only MockUSDC also uses 6 decimals.
1 USDC = 1000000 base units
Browser Transaction Flow
When the wallet is connected to Arc Testnet and the market is open:
- Parse the user-entered USDC amount with 6 decimals.
- Submit
approve(SignalArcMarket, amount) to the Arc Testnet USDC ERC20 interface.
- Wait for the approval receipt.
- Submit
openPosition(outcome, amount) to SignalArcMarket.
- Wait for the open-position receipt.
- Show Arcscan transaction links.
The backend exposes local/testnet metadata at GET /arc/contract. The response marks the deployment as a prototype and production_approved: false.
Explicit Limitations
- Prototype/testnet only.
- Not audited.
- Not production custody.
- Not production settlement.
- No Arc mainnet deployment.
- No Circle production wallet or custody integration.
- No oracle integration.
- No dispute flow.
- Payout behavior is fixed 1:1 in the prototype contract.
- Resolver is a single address.
- Any Arc or Circle behavior not implemented or not documented in official sources is unknown / not documented.
