How this service works
The premier global index of 1,069 monetized MCP nodes across 205 specialized subdomains. Gasless USDC runtime settlements via x402 V2 Spec on Base L2. Save 95% token context.
Output
Returns a result object indicating the success or failure of the cross-chain relay, including transaction or execution status, any receipt or confirmation identifiers, and error details if the relay failed.
Example use cases
DeFi cross-chain token bridge
“I need to relay a contract call from Ethereum to Polygon for a DeFi swap — here's the calldata string: '{"action":"swap","token":"USDC","amount":"500","from":"ethereum","to":"polygon"}'. Can you process it through the cross-chain relayer?”
Multi-chain NFT contract execution
“Execute this cross-chain contract interaction to mint an NFT on Avalanche triggered from an Ethereum contract — process this payload: '{"type":"mint","from":"ethereum","to":"avalanche","contract":"0xDEF...","params":"0x..."}' via the contract relayer.”
Cross-chain governance vote relay
“I need to relay a governance vote transaction from Binance Smart Chain to Arbitrum — please process this cross-chain contract data string: '{"vote":"yes","proposal":42,"from":"bsc","to":"arbitrum","contract":"0x123..."}'.”
Technical details
Endpoint
POSThttps://api.m2mcent.com/cross-chain-contract-relayer-mcp/api/process?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically relay or trigger smart contract calls across different blockchain networks without managing the underlying bridge infrastructure yourself. Best suited for agents orchestrating multi-chain DeFi, NFT, or governance workflows where cross-chain contract execution is required.
Side effects
- Invalid or malformed data string returns a parsing error
- Unsupported source or destination chain results in relay failure
- Network congestion or chain unavailability causes timeout
- Insufficient gas or execution budget on destination chain leads to revert
- Payment not received (x402 flow) results in 402 Payment Required response
