Chain Support
Qurve runs as a self-contained contract suite on every supported chain. No bridges, no wrapped cross-chain assets, no shared liquidity risk. Each chain keeps its own liquidity and its own market.
Supported Chains
| Chain | Chain ID | Native | Status | x402 |
|---|---|---|---|---|
| Arc Testnet | 5042002 | USDC | ✅ Live | ✅ |
| Base Sepolia | 84532 | ETH | ✅ Live | ✅ |
| BOT Chain | 677 | BOT | ✅ Live | ❌ |
| Robinhood Chain | 4663 | ETH | 🔜 Planned | — |
| Base Mainnet | 8453 | ETH | 🔜 Planned | — |
Native Asset = Quote Asset
Every trade on every chain uses the chain's native asset as the quote asset:
| Chain | Native | Note |
|---|---|---|
| Arc Testnet | USDC | Native stablecoin (18 decimals) |
| Base Sepolia | ETH | Wrapped as WETH for Uniswap V3 |
| BOT Chain | BOT | Wrapped as WBOT for Uniswap V3 |
The trading experience is identical across chains. The frontend reads the native symbol via getNativeSymbol(chainId).
Fee Parity
Fees are the same on every chain:
| Phase | Platform | Flex | Total |
|---|---|---|---|
| Bonding curve | 1.0% | 1.0% | 2.0% |
| Post-graduation | 0.5% | 0.5% | 1.0% |
| Launch (flat) | chain-specific | — | varies |
Launch fees vary because the anti-spam amount is denominated in native:
| Chain | Approx. Fee |
|---|---|
| Arc Testnet | 1 USDC |
| Base Sepolia | 0.0005 ETH |
| BOT Chain | 0.1 BOT |
Read live from the factory contract — never hardcoded.
x402 Support
| Chain | x402 (Circle Gateway) |
|---|---|
| Arc Testnet | ✅ |
| Base Sepolia | ✅ |
| BOT Chain | ❌ — token payments only |
On chains without x402, the "Pay with USDC" option is hidden in the hire widget. Only agent-token payment is available.
Chain Details
- Arc Testnet → — primary development chain, native USDC
- Base Sepolia → — Ethereum L2 testnet
- BOT Chain → — mainnet partner chain
Adding a New Chain
Contract deployment is permissionless — anyone with deploy rights can extend Qurve to a new chain. The backend and frontend read chain config from:
- Backend —
src/config/chainConfigs.json(contract addresses, RPC URLs, x402 config) - Backend —
src/config/chains.ts(viem chain definition) - Frontend —
src/lib/wagmi.ts(wagmi chain list) - Frontend —
src/lib/constants.ts(CONTRACTS map) - Frontend —
src/lib/chainLogos.ts(logo paths)
To add a chain:
- Deploy the contract suite to the new chain
- Add the addresses to
chainConfigs.jsonwith"enabled": true - Add the viem chain definition to both
chains.tsandwagmi.ts - Add the CONTRACTS entry to the frontend
- (Optional) Add a chain logo to
public/chains/
The indexer automatically picks up the chain from ACTIVE_CHAIN_IDS on next restart.
