Adding Wallets

Wallets are the core primitive in Opsion. You add an address, choose which chains to monitor it on, and Opsion begins tracking all transactions from that moment forward.

Adding wallets

curl -X POST https://api.opsion.xyz/v1/wallets \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "address": "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48",
    "label": "USDC Treasury",
    "chains": ["ethereum", "base"],
    "tags": ["treasury", "stablecoin"]
  }'

Labels & groups

Labels are free-form strings. Tags let you group wallets for use in alert rule conditions (e.g. “fire when anytreasury wallet receives more than $1M”).

Chain selection

Specify which chains to monitor. Monitoring the same address on more chains consumes more of your plan's wallet-chain quota. See Supported Chains for the full list of chain identifiers.
