Anatomy of the Wallet Transactions endpoint
Returns a wallet's transaction history as decoded, human-readable events. Each transaction includes its type, direction, asset transfers, fees, and links — filterable by type, chain, and time range and paginated for large histories.

Everything the Wallet Transactions endpoint gives you to ship a real integration — filters, coverage, and predictable limits.
Query history like a database
Full-text search plus filters for type, asset, chain and time range narrow a wallet's entire history to exactly what you need.
- filter[search_query] — full-text, 2–64 chars
- filter[operation_types] — trade, send, deposit…
- filter[asset_types] — fungible or nft
- filter[min_mined_at] / max_mined_at — time range
Cursor paging for long histories
Page through years of activity with stable cursors — no offset drift.
- page[size] up to 100 (default 100)
- page[after] cursor
- Follow links.next to walk the history
15 operation types, human-readable
Calldata is decoded into readable actions, so you never parse raw input yourself.
- approve, bid, burn, claim, delegate, deploy, deposit…
- …execute, mint, receive, revoke, send, trade, withdraw
- dapp name, method and icon on interactions
Multi-chain and testnet
History spans 40+ chains; scope it with filters or query everything at once.
- filter[chain_ids] to scope networks
- X-Env: testnet header for test data
- Solana NFT transactions not yet supported
