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>           # ETH balance
morph-agent onchain rpc nonce --address 0x<addr>             # Transaction count
morph-agent onchain rpc gas                                   # Current gas price
morph-agent onchain rpc block                                 # Latest block
morph-agent onchain rpc block --number 12345678               # Specific block
morph-agent onchain rpc tx --hash 0x<txhash>                  # Transaction details
morph-agent onchain rpc call --to 0x<addr> --data 0x<hex>    # Read-only contract call

Morph L2 gas is very low (~0.021 Gwei).

onchain explorer — Blockscout Historical Queries

morph-agent onchain explorer address-info -a 0x<addr>        # Address overview
morph-agent onchain explorer txs -a 0x<addr> [--limit 20]    # Transaction history
morph-agent onchain explorer tokens -a 0x<addr>              # Token holdings
morph-agent onchain explorer tx --hash 0x<txhash>            # Transaction details
morph-agent onchain explorer token-search --query USDC       # Search tokens
morph-agent onchain explorer token-info --token 0x<addr>     # Token details
morph-agent onchain explorer contract -a 0x<addr>            # Contract info + ABI

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                              # List supported fee tokens
morph-agent onchain altfee token-info --id 6                   # Specific token details
morph-agent onchain altfee estimate --id 6 [--gas-limit 21000] # Estimate fee

Recommended Fee Token IDs (Mainnet)

ID	Token
4	BGB
5	USDT
6	USDC

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>        # Check if delegated

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
