Mantle is an EVM-compatible scaling solution for Ethereum, built on the OP Stack as a ZK validity rollup. It produces a block every 2 seconds. Its native token is MNT. Block explorer: https://mantlescan.xyz Mantle’s own developer documentation: https://docs.mantle.xyz

Network Support

Network	Full History / Archive	HTTPS	WSS
Mantle Mainnet	Blocks, receipts and logs ✅ to genesis State and Debug ❌ (last 128 blocks)	✅	✅

Mantle Mainnet keeps historical state for the last 128 blocks, about 4 minutes at Mantle’s 2-second block time. State methods (eth_call, eth_createAccessList, eth_estimateGas, eth_getBalance, eth_getCode, eth_getProof, eth_getStorageAt, eth_getTransactionCount, eth_simulateV1) and the Debug API work for blocks inside that window. Older blocks return JSON-RPC error -32000 with a message that contains historical state <root> is not available.

The Trace API (trace_*) is not available on Mantle. Use the Debug API for call traces.

WebSocket clients MUST respond to server ping frames, otherwise the connection will be closed and re-established every minute.

Getting Started

Send a request to check that your endpoint works. Replace <YOUR_API_KEY_HERE> with the key from your endpoint in the Validation Cloud app.

curl https://mainnet.mantle.validationcloud.io/v1/<YOUR_API_KEY_HERE> \
    -X POST \
    -H "Content-Type: application/json" \
    -d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":0}'

Connect over WebSocket:

wscat -c wss://mainnet.mantle.validationcloud.io/v1/wss/<YOUR_API_KEY_HERE>
