How this service works

Same-owner confidence (0-1) and verdict for two Solana wallets: direct transfers between them, first funders (one step back), age and activity of the new wallet, x402 payments it has received, risk flags. Thin evidence gives UNCERTAIN. Built for x402 trust monitors checking a payout-wallet change.

Output

Returns a same-owner confidence score (0–1), a verdict (e.g. LIKELY_SAME, UNLIKELY_SAME, UNCERTAIN, or LIKELY_ROTATION in payout_rotation context), evidence signals including direct transfers between the two wallets, first funder overlap (one hop back), the new wallet's age and activity metrics, any x402 payments it has received, and risk flags. Thin or absent on-chain evidence yields an UNCERTAIN verdict. Response format can be structured JSON, a short LLM-readable briefing, or both.

Example use cases

Payout wallet rotation fraud check

“Our API partner just requested we change their payout address from 7dNk...aQ1R to 3pBf...wL9M — can you run a same-owner check with payout_rotation context and tell me the confidence score and verdict before we approve it?”

x402 trust monitor for new payee

“We're receiving x402 payments from a new wallet HsW2...kT4P but suspect it might be connected to a previously flagged address 9cXv...jY6N — check if these two Solana wallets are likely the same owner and return any risk flags.”

Freelancer wallet change verification

“A contractor says they lost access to their old wallet FmP8...rA3K and wants payments sent to their new address 2gLq...nD5V instead — can you check the same-owner confidence between these two Solana addresses so I know if it's really them?”

Technical details

Endpoint

When to prefer

Choose this endpoint when you need to verify whether two specific Solana wallets share an owner — especially in x402 payment contexts where a payout wallet change needs trust validation. It is purpose-built for wallet rotation fraud detection and provides richer linkage evidence (first funders, x402 history, age signals) than generic blockchain explorers. Prefer it over general wallet enrichment endpoints when the specific question is same-owner identity, not portfolio or DeFi analysis.

Side effects

Invalid or malformed Solana base58 address returns a 400 error
Wallet with no on-chain history yields UNCERTAIN verdict with low confidence
Token account resolution failure if a non-owner address is submitted
Insufficient on-chain data to establish linkage results in low-confidence UNCERTAIN
Network timeouts or RPC errors from Solana data providers may cause 5xx responses
Wallets with purely private/off-chain interactions cannot be linked
