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/api/wallets \
  -H "Authorization: Bearer opsk_your_key_here" \
  -H "Content-Type: application/json" \
  -d '{
    "address": "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48",
    "chain": "ethereum",
    "label": "USDC Treasury",
    "tags": ["treasury", "stablecoin"]
  }'

Labels & groups

Labels are free-form strings. Tags let you group wallets for filtering and alert targeting (e.g. fire when anywallet tagged “treasury” receives more than $1M).

Chain selection

Each wallet monitors a single address on a single chain. To monitor the same address across multiple chains, create one wallet entry per chain. See Supported Chains for all chain identifiers.
