All projects on Solana matching “transactions”

Coinbase-hosted facilitator that verifies and settles x402 payments, with KYT and OFAC screening on each transaction. Also runs the CDP Bazaar discovery catalog.

Solana transaction preview BEFORE signing: simulate an unsigned or signed legacy/v0 transaction (address lookup tables resolved) and get SOL and SPL/Token-2022 balance changes for your wallet, programs invoked (known/unknown), fee estimate and red flags (token approvals, authority/owner changes, close-to-other, wallet reassign, >90% SOL loss, simulation failure). JSON body. Optional Pre-Sign Brief

Repair a failing Solana transaction: exact cause, rebuilt unsigned transaction, simulation proof, verification.

Solana swap execution for AI agents. Returns an UNSIGNED swap transaction on the best venue after fees, Jito tip and expected sandwich loss, with the plan, a simulation and the net-benefit arithmetic to verify before signing, plus the same Safe / Protect / Refuse verdict as /analyse. Needs taker: the mainnet wallet that signs and funds the trade. Never signs or holds keys. Full contract: GET /v1/a

Run before setting a priority fee. Gives the price in the exact unit Compute Budget expects (micro-lamports per compute unit) and the total cost in SOL, so a unit mix-up never overpays. Turns recent on-chain priority fees into three prices: cheap, normal and fast. Pass your transaction to get its compute limit and exact cost at each price.

SEC Form 4 insider transaction query

Read-only Solana financial-action firewall: decode and simulate an unsigned transaction, bind observed effects to declared intent and policy, and return a signed PASS/FAIL/REVIEW receipt

Use this before signing a transaction for a Solana program: who can change its code (single key, Squads multisig with threshold and time lock, DAO, or immutable), when it last changed, verified build, security.txt. Instant, per request.

Processed transactions that touch specified accounts or programs before finalization.
