How Sei processes a transaction from wallet to chain
Sei processes your transaction when your wallet signs it, a node checks it, validators order the block, and the chain records it in an explorer.

Sei handles many transactions at once through parallel execution and a fast consensus. That design keeps the network moving, but your transaction still goes through the same checkpoints from wallet to final block.
What do you need before you start?
Before you send, set up a wallet that supports Sei and select the Sei network. If the network is wrong, the transaction will not reach Sei validators. Keep a small amount of SEI in the same wallet to cover the network fee.
How does Sei process your transaction?
Sei uses parallel execution and a fast consensus to process many transactions at once. Parallel execution lets Sei run independent transactions at the same time. An RPC node is a server that accepts transactions from wallets and passes them into the network.
- 1Sign in your walletYour wallet uses your key to authorize the amount, the recipient, and the network.
- 2Send it to a Sei RPC nodeYour wallet broadcasts the signed transaction to an RPC node, which acts as the entry point to the network.
- 3Let the node run its checksThe node verifies the signature, the account sequence number (or nonce on EVM transactions), and your balance before it shares the transaction with other nodes.
- 4Validators order the transactionValidators agree on the block through Sei's consensus and decide the order of transactions inside it.
- 5Sei executes the transactionsSei runs non-conflicting transactions in parallel and sequences conflicting ones to protect the shared state.
What happens after it is confirmed?
Once the block is final, your transaction becomes part of the chain record. A Sei explorer shows it by transaction hash, along with its block and status. You can save the hash if you need a record for accounting or support.
Frequently asked questions
It reverts and its changes are undone. The network fee is usually not refunded because validators already did the work.
Sei's consensus is built for speed, so confirmation usually comes quickly. Busy periods can take longer.
Once broadcast, a transaction usually cannot be canceled. Some wallets let you replace it with a new one at a higher fee.
Ethereum processes transactions one after another. Sei runs non-conflicting transactions in parallel and sequences the ones that conflict.
