What Is Transaction Hash (TxHash)?
Definition
A transaction hash is a unique identifier for a blockchain transaction — a long string of characters that lets you look up any transaction on a block explorer to verify its status and details.
Every blockchain transaction gets a unique hash (also called TxID or TxHash). This hash is like a receipt — it proves the transaction happened and lets anyone verify the details.
- Solana — Base58 encoded string, ~88 characters. Example: 5VERv8NMvzbJMEkV8xnrLkEaWRtSz9CosKDYjCJjBRnbJLgp8uirBgmQpjKhoR4tjF3ZpRzrFmBV6UjKdiSZkQUW
- Ethereum/Base — hex string starting with 0x, 66 characters. Example: 0x1234...abcd
- Status — success or failed
- From/To — sender and receiver addresses
- Amount — tokens or currency transferred
- Gas fee — how much the transaction cost
- Block number — which block included the transaction
- Timestamp — when it was confirmed
When using CoinDevTools, you receive a transaction hash after every operation (token creation, authority revocation, pool creation, LP burn). Save these hashes — they're your permanent proof of each action.

What Is a Block Explorer?Related Terms
Blockchain
A blockchain is a distributed, immutable digital ledger that records transactions across a network of computers — the foundational technology behind all cryptocurrencies and tokens.
Gas (Transaction Fee)
Gas is the fee paid to blockchain validators for processing transactions. On Ethereum it's measured in gwei, on Solana it's called a priority fee — both compensate the network for computation.
Block Explorer
A block explorer is a web tool that lets you search and view all transactions, addresses, tokens, and smart contracts on a blockchain — like a search engine for on-chain data.
Mainnet
Mainnet is the live, production blockchain where real transactions with real value occur — as opposed to testnets (devnet, Sepolia) which use fake tokens for testing.
