Learn about NFT sales, DeFi swaps, staking, and 100+ supported blockchain transaction types. ## Understanding Transaction Types Transaction types represent different blockchain actions decoded by our system. Each transaction type corresponds to specific on-chain activities like NFT minting, bidding, or staking. Below is the full list of transaction types supported: ```yaml [expandable] theme={"system"} - UNKNOWN - NFT_BID - NFT_BID_CANCELLED - NFT_LISTING - NFT_CANCEL_LISTING - NFT_SALE - NFT_MINT - NFT_AUCTION_CREATED - NFT_AUCTION_UPDATED - NFT_AUCTION_CANCELLED - NFT_PARTICIPATION_REWARD - NFT_MINT_REJECTED - CREATE_STORE - WHITELIST_CREATOR - ADD_TO_WHITELIST - REMOVE_FROM_WHITELIST - AUCTION_MANAGER_CLAIM_BID - EMPTY_PAYMENT_ACCOUNT - UPDATE_PRIMARY_SALE_METADATA - ADD_TOKEN_TO_VAULT - ACTIVATE_VAULT - INIT_VAULT - INIT_BANK - INIT_STAKE - MERGE_STAKE - SPLIT_STAKE - SET_BANK_FLAGS - SET_VAULT_LOCK - UPDATE_VAULT_OWNER - UPDATE_BANK_MANAGER - RECORD_RARITY_POINTS - ADD_RARITIES_TO_BANK - INIT_FARM - INIT_FARMER - REFRESH_FARMER - UPDATE_FARM - AUTHORIZE_FUNDER - DEAUTHORIZE_FUNDER - FUND_REWARD - CANCEL_REWARD - LOCK_REWARD - PAYOUT - VALIDATE_SAFETY_DEPOSIT_BOX_V2 - SET_AUTHORITY - INIT_AUCTION_MANAGER_V2 - UPDATE_EXTERNAL_PRICE_ACCOUNT - AUCTION_HOUSE_CREATE - CLOSE_ESCROW_ACCOUNT - WITHDRAW - DEPOSIT - TRANSFER - BURN - BURN_NFT - PLATFORM_FEE - LOAN - REPAY_LOAN - ADD_TO_POOL - REMOVE_FROM_POOL - CLOSE_POSITION - UNLABELED - CLOSE_ACCOUNT - WITHDRAW_GEM - DEPOSIT_GEM - STAKE_TOKEN - UNSTAKE_TOKEN - STAKE_SOL - UNSTAKE_SOL - CLAIM_REWARDS - BUY_SUBSCRIPTION - SWAP - INIT_SWAP - CANCEL_SWAP - REJECT_SWAP - INITIALIZE_ACCOUNT - TOKEN_MINT - CREATE_APPARAISAL - FUSE - DEPOSIT_FRACTIONAL_POOL - FRACTIONALIZE - CREATE_RAFFLE - BUY_TICKETS - UPDATE_ITEM - LIST_ITEM - DELIST_ITEM - ADD_ITEM - CLOSE_ITEM - BUY_ITEM - FILL_ORDER - UPDATE_ORDER - CREATE_ORDER - CLOSE_ORDER - CANCEL_ORDER - KICK_ITEM - UPGRADE_FOX - UPGRADE_FOX_REQUEST - LOAN_FOX - BORROW_FOX - SWITCH_FOX_REQUEST - SWITCH_FOX - CREATE_ESCROW - ACCEPT_REQUEST_ARTIST - CANCEL_ESCROW - ACCEPT_ESCROW_ARTIST - ACCEPT_ESCROW_USER - PLACE_BET - PLACE_SOL_BET - CREATE_BET - NFT_RENT_UPDATE_LISTING - NFT_RENT_ACTIVATE - NFT_RENT_CANCEL_LISTING - NFT_RENT_LISTING - FINALIZE_PROGRAM_INSTRUCTION - UPGRADE_PROGRAM_INSTRUCTION - NFT_GLOBAL_BID - NFT_GLOBAL_BID_CANCELLED - EXECUTE_TRANSACTION - APPROVE_TRANSACTION - ACTIVATE_TRANSACTION - CREATE_TRANSACTION - REJECT_TRANSACTION - CANCEL_TRANSACTION - ADD_INSTRUCTION - ATTACH_METADATA - REQUEST_PNFT_MIGRATION - START_PNFT_MIGRATION - MIGRATE_TO_PNFT - UPDATE_RAFFLE - CREATE_POOL - ADD_LIQUIDITY - WITHDRAW_LIQUIDITY ``` If you'd like us to parse a transaction type that isn't listed above, feel free to reach out on our [Discord](https://discord.com/invite/6GXdee3gBj). ## Mapping Transaction Types to Sources Each transaction type is generated by specific program sources. Understanding these relationships helps identify which programs are triggering particular transaction types. The mappings below illustrate the relationship between sources (programs) and specific transaction types: * **Type-to-Source**: Shows which programs generate a specific transaction type * **Source-to-Type**: Shows all transaction types a specific program can generate For example, **NFT\_GLOBAL\_BID** transactions are generated by **MAGIC\_EDEN** or **SOLANART**, while **CANDY\_MACHINE\_V2** exclusively generates **NFT\_MINT** events. ## Type-to-Source Reference This mapping shows which program sources can generate each transaction type. ```json [expandable]

webhook listeners, you can filter for specific transaction types of interest. Here's a simple example of how to listen for NFT sale events: ```javascript theme={"system"} // Example webhook handler for NFT sales app.post('/webhook', (req, res) => { const event = req.body; // Filter for NFT sale transactions if (event.type === 'NFT_SALE') { console.log('NFT Sale detected!'); console.log('Seller:', event.seller); console.log('Buyer:', event.buyer); console.log('Price:', event.amount); console.log('NFT:', event.nft?.mint); // Process the sale event // ... } res.status(200).send('OK'); }); ``` You can use the Type-to-Source and Source-to-Type mappings to anticipate which programs will generate specific transaction types.
