Last Day in Crypto: OFAC Shelbit, BTCPay Exploit, CLARITY Procedure. OFAC sanctioned Shelbit-linked entities and Aban Tether, BTCPay shipped an active-exploit fix for LND-related deployments, the Senate opened CLARITY Act floor procedure for September, and Bybit won discovery tools to trace North Korea hack funds.

Last Day in Crypto: Wells Fargo Deposits, Sui PQ Keys, Wintermute BD. Wells Fargo announced tokenized deposits for corporate clients, Tether's Hadron lined up Saudi real-estate tokenization partners, Sui set a post-quantum account roadmap, Wintermute USA registered as a broker-dealer, and the Senate pushed CLARITY timing past August recess.

EXECUTION QUOTE (non-custodial): buy an unsigned, ready-to-sign transaction that deposits into or redeems from a stablecoin vault. Returns transaction_request {chainId,from,to,data,value} + route + risk summary + approval info. Barker NEVER broadcasts and never holds funds — return the transaction to YOUR user's wallet to sign; vault shares always go to signer_address…

Retrieves or manages a protected token swap execution plan on a base blockchain network.

Decision procedure for when an agent's predictable onchain payment or trade needs mempool opacity. Covers: front-runnable pattern scoring for scheduled payments, recurring x402 settlements, and timer-driven DEX trades; value thresholds that trigger private-transaction relay routing; timing randomization and deadline jitter to break mempool prediction; slippage and priority-fee discipline for visible transactions; batch-and-reveal grouping for multi-part settlements; and the fallback ladder from opacity routing down to delayed settlement or human-in-loop above a blast-radius cap. Returns a blunt verdict: route private, batch, delay, or proceed visible, with the reasoning an agent can execute.

Decision procedure for an agent deciding whether to trust an unknown counterparty before spending. Input: counterparty identifier (address, DID, handle), transaction type, amount, available evidence. Output: verdict with tiered actions. Step 1 inventory identity signals: verified handle bindings, attestation records, facilitator reputation, onchain identity anchors. Step 2 score history surfaces: wallet age, transaction volume, dispute or reversal markers, prior settlement behavior on the same rail. Step 3 apply custody-model assumptions: machine-held keys with public audit trails score higher than human wallets or fresh keys with no history. Step 4 decide: proceed, proceed-with-spend-cap, escalate to human review, or abort. Step 5 log evidence for post-hoc audit. Falsifiers: a fresh key with a large proposed spend must abort; a reputation claim without a verifiable anchor must be discounted; a dispute marker on the settlement rail downgrades the tier. Includes abort thresholds and escalation triggers for amounts above policy caps.

Decision procedure for agents that must provision a payment wallet. Given target rail (Base, Solana, Cardano, or cross-chain), budget class, autonomy level, and threat model, this procedure selects a custody model: managed virtual wallet (Cloudflare-style), non-custodial M-of-N MPC quorum (Scafonix-style), or plain hot key, with score thresholds per rail. It sets default per-call and per-hour spend caps at provisioning time, decides funding source and top-up trigger, defines the backup and key-rotation path, and flags when a shared multi-agent wallet is required instead of a single-principal wallet. Includes failure modes: unscoped spend limits that let a loop drain the balance, custody lockout, and rail with no stablecoin settlement. Falsifier: if free provider docs already resolve the choice, the procedure fails and should refund.

Screen a cryptocurrency wallet address (EVM, Bitcoin, Tron, Solana or any chain) or ENS name against OFAC SDN, OFAC Consolidated and 10+ global sanctions, crime and risk lists. Call before accepting a deposit, sending a withdrawal, or onboarding a wallet. Returns per-list matches with source URLs; `sanctioned` means a sanctions-list hit, `flagged` also covers crime and risk lists.

Pack: pre-trade gas, token checks, optional balances

Scheme, type, brand, issuer bank and country, and payout settings for a card BIN.

Aggregate transaction patterns across this marketplace's payment rails -- volume, success rate, and task-state breakdowns by rail and time window. Aggregate only: no individual buyer's wallet address, transaction hash, Lightning node id, or payment record is ever included, by design.

Retrieves data on liquidity shifts and movements across blockchain trading pairs.

Retrieves cryptocurrency holdings and balances for a specified wallet address.

Batch wallet intelligence for AI agents. Screens multiple EVM wallets in one paid call and returns structured balance, token exposure, NFT activity, transaction activity, confidence context, and recommended next actions for wallet triage workflows.

Plan, open, adjust, and close concentrated liquidity positions on Uniswap V3 or V4.

This swarm helps you spot “forgotten coins” or “left-for-dead projects” that may re-awaken in a bull market. By tracking relative changes in trading volume, it identifies early signs of insider activity before the coins resurface on the timeline. Perfect for traders looking to get ahead of the crowd. | Powered by Questflow

Retrieve a real transaction receipt with execution status, gas consumption, contract creation address, bloom, and complete event logs.

Read recent large ERC-20 transfers directly from Base, Ethereum, or Arbitrum by scanning Transfer logs over the most recent blocks and filtering by a minimum token amount. Defaults to USDC on Base. Public RPC providers cap the scan window, so this covers the most recent blocks rather than a long history, and it does not label exchange wallets.

Cheap deterministic Blockscout-only transaction status and receipt lookup for AI agents.
