RPC reference

Nanvil adds dev JSON-RPC methods alongside standard neo-go RPC.

nanvil_mine

Mine one or more blocks.

Params: [blocks] (optional, default 1)

Example:

{"jsonrpc":"2.0","id":1,"method":"nanvil_mine","params":[2]}

Alias: evm_mine

nanvil_setAutomine / nanvil_getAutomine

Enable or query auto-mining on transaction relay.

{"jsonrpc":"2.0","id":1,"method":"nanvil_setAutomine","params":[true]}

nanvil_impersonateAccount

Register an address for dev witness bypass (see impersonation.md).

{"jsonrpc":"2.0","id":1,"method":"nanvil_impersonateAccount","params":["NV..."]}

nanvil_stopImpersonatingAccount

Remove an impersonated address.

nanvil_autoImpersonateAccount

Enable/disable auto-impersonation for all signers.

{"jsonrpc":"2.0","id":1,"method":"nanvil_autoImpersonateAccount","params":[true]}

nanvil_increaseTime

Advance block timestamp and mine one block.

Params: [seconds]

Alias: evm_increaseTime

nanvil_setNextBlockTimestamp

Set absolute timestamp for the next mined block.

nanvil_setBalance

Not implemented. Returns an error directing callers to fund accounts via GAS transfer from prefunded dev/validator accounts.

nanvil_snapshot / nanvil_revert

Create and revert to named snapshots (height-based; chain must be stopped for revert).

nanvil_reset

Reset chain (requires restart; use snapshots for hot revert).

nanvil_dropTransaction

Remove a transaction from the mempool by hash.

nanvil_nodeInfo

Return dev accounts, fork metadata, and cache stats.

Standard neo-go RPC

All standard methods work: invokefunction, sendrawtransaction, getblockcount, invokefunctionhistoric, etc.
