nulucre_get_stellar_wallet_score
Get Stellar Wallet Reputation Score
Get a 0-100 trust score for a Stellar wallet address (G...) from Nulucre, a live Stellar-native wallet reputation oracle.
The score is computed from 8 signals pulled directly from the Stellar Horizon API and Stellar Expert — account age, transaction volume, asset diversity, SDEX DEX participation, network trust, claimable balance activity, Soroban contract interactions, and liquidity pool participation, plus a spam detection penalty. No EVM data is used.
Every score includes a real-time sanctions screening result against the OFAC SDN, OFAC Non-SDN, EU Financial Sanctions, and UN Security Council Sanctions lists. A wallet matching any of these lists automatically receives a score of 0 and status BLACKLISTED.
Use this tool to assess counterparty risk before an agent interacts with or pays a Stellar wallet — for example before executing a payment, approving a swap counterparty, or evaluating a new account.
Args:
- g_address (string): Stellar wallet address starting with 'G' (56 characters)
- signed (boolean): If true, request an ECDSA-P256 signed score for independent
verification via Nulucre's public JWKS endpoint (default: false)
- response_format ('markdown' | 'json'): Output format (default: 'markdown')
Returns:
