| name | morphcli-chain |
| description | Morph L2 chain operations via morphcli — RPC queries (balance, nonce, gas price, block, tx details, contract call), Blockscout explorer (address info, tx history, token holdings, contract info, token search), alt-fee gas payment with ERC-20 tokens (tx type 0x7f), and EIP-7702 delegation management (delegate, send, batch, revoke). Use this skill whenever the user wants to query Morph chain data, look up transactions or blocks, check gas prices, explore address history on Morph, search or inspect tokens, query contract state, pay gas fees with ERC-20 tokens instead of ETH, or manage EIP-7702 delegations. Trigger when the user mentions 'Morph RPC', 'check nonce', 'gas price on Morph', 'look up tx hash', 'Morph explorer', 'Blockscout', 'token holders', 'alt-fee', 'altfee', 'pay gas with USDC', 'pay gas with BGB', 'tx type 0x7f', 'EIP-7702', '7702 delegation', 'batch call', 'revoke delegation', or wants any on-chain read from Morph L2. |
morphcli chain — RPC, Explorer, Alt-Fee & EIP-7702 on Morph L2
morph-agent onchain has four subgroups: rpc (real-time), explorer (Blockscout historical), altfee (ERC-20 gas payment), 7702 (EIP-7702 delegation).
- Text output by default; add
--json for structured JSON
onchain rpc — Real-time Chain Queries
morph-agent onchain rpc balance --address 0x<addr>
morph-agent onchain rpc nonce --address 0x<addr>
morph-agent onchain rpc gas
morph-agent onchain rpc block
morph-agent onchain rpc block --number 12345678
morph-agent onchain rpc tx --hash 0x<txhash>
morph-agent onchain rpc call --to 0x<addr> --data 0x<hex>
Morph L2 gas is very low (~0.021 Gwei).
onchain explorer — Blockscout Historical Queries
morph-agent onchain explorer address-info -a 0x<addr>
morph-agent onchain explorer txs -a 0x<addr> [--limit 20]
morph-agent onchain explorer tokens -a 0x<addr>
morph-agent onchain explorer tx --hash 0x<txhash>
morph-agent onchain explorer token-search --query USDC
morph-agent onchain explorer token-info --token 0x<addr>
morph-agent onchain explorer contract -a 0x<addr>
Morph Mainnet Token Addresses
| Symbol | Address | Decimals | Note |
|---|
| USDC | 0xCfb1186F4e93D60E60a8bDd997427D1F33bc372B | 6 | Native USDC (CLI default) |
| USDC.e | 0xe34c91815d7fc18A9e2148bcD4241d0a5848b693 | 6 | Bridged version |
| USDT | 0xe7cd86e13AC4309349F30B3435a9d337750fC82D | 6 | Native USDT |
| BGB | 0x389C08Bc23A7317000a1FD76c7c5B0cb0b4640b5 | 18 | |
| WETH | 0x5300000000000000000000000000000000000011 | 18 | |
When the user says "USDC", use native USDC (0xCfb1...72B) unless bridged version is explicitly requested.
onchain altfee — Pay Gas with ERC-20 (tx type 0x7f)
Morph supports paying gas with ERC-20 tokens via tx type 0x7f. TokenRegistry predeploy at 0x5300000000000000000000000000000000000021.
morph-agent onchain altfee tokens
morph-agent onchain altfee token-info --id 6
morph-agent onchain altfee estimate --id 6 [--gas-limit 21000]
Recommended Fee Token IDs (Mainnet)
Add --altfee <id> to any write command to use alt-fee:
morph-agent wallet transfer --to 0x... --amount 0.1 --altfee 5
Network Info
| Network | Chain ID | RPC | Blockscout API |
|---|
| Morph Mainnet | 2818 | https://rpc-quicknode.morph.network | https://explorer-api.morph.network/api/v2 |
| Morph Hoodi | 2910 | https://rpc-hoodi.morph.network | https://explorer-api-hoodi.morph.network/api/v2 |
onchain 7702 — EIP-7702 Delegation Query
morph-agent onchain 7702 delegate --address 0x<addr>
Output shows isDelegated: true/false and delegateContract address (e.g., SimpleDelegation 0x6Dbe...C1E5).
To use EIP-7702 delegation in write commands, add --eip7702:
morph-agent wallet transfer -w <wallet> --to 0x<addr> --amount 0.1 --eip7702
Both PK and SL wallets support --eip7702. SL wallets sign EIP-7702 authorization via BGW EthSign:{hash}.
Note: For self-delegation (sender == authority), auth nonce must be txNonce + 1 due to geth nonce ordering. This is handled automatically by morphcli.
Safety
- Fee estimates include 10% buffer but do NOT include L1 data fee
- Always confirm with user before broadcasting
