dokrypt replay

Usage

dokrypt replay tx <tx-hash> [flags]
dokrypt replay block <block-number> [flags]
dokrypt replay trace <tx-hash> [flags]

Subcommands

`replay tx`

Fetch a transaction from a live network, fork the chain at that block, and re-execute it locally. Shows transaction details, gas comparison, revert reasons, and optional execution trace.

dokrypt replay tx 0xabc123... --network arbitrum
dokrypt replay tx 0xabc123... --network mainnet --verbose

Flag	Default	Description
`--network`	`mainnet`	Source network to fetch tx from
`--chain`		Target local chain
`--block`		Custom fork block (default: one block before tx)
`--verbose`	`false`	Show full execution trace

Output includes:

Transaction details (from, to, value, gas, method selector)
Transaction status (success/reverted)
Event count
Gas comparison (original vs replayed)
Revert reason (if applicable)

`replay block`

List all transactions in a specific block from a live network.

dokrypt replay block 200000000 --network arbitrum
dokrypt replay block 19000000 --network mainnet --limit 20

Flag	Default	Description
`--network`	`mainnet`	Source network
`--chain`		Target local chain
`--limit`	`50`	Max transactions to display

`replay trace`

Get a detailed execution trace of a transaction showing all internal calls.

dokrypt replay trace 0xabc123... --network arbitrum

Flag	Default	Description
`--network`	`mainnet`	Source network
`--chain`		Target local chain for tracing

The trace shows nested call hierarchy with:

Call type (CALL, DELEGATECALL, STATICCALL, CREATE)
From/to addresses
Method selectors
ETH value transferred
Gas used per call
Revert reasons for failed calls

Supported Networks

All networks from dokrypt fork are supported:

Network	RPC

You can also pass a custom RPC URL directly.

Examples

Debug a reverted transaction on Arbitrum:

dokrypt replay tx 0xfailed... --network arbitrum --verbose

Inspect a block on Ethereum:

dokrypt replay block 19500000 --network mainnet

Trace internal calls of a DeFi transaction:

dokrypt replay trace 0xswap... --network arbitrum
