Auth method: Signed (HMAC) — this endpoint requires the full set of signed headers: x-access-id, x-request-id, x-timestamp, and an HMAC-SHA256 authorization signature. See Authentication.

Registers an address with Tender’s deposit monitor. Once registered, any deposit detected on this address triggers a SUB_USER_WALLET_TRANSACTION_DETECTED webhook to your server.

Example

const res = await fetch(`${BASE}/wallet/filter`, {
  method: 'POST',
  headers: makeHeaders(),
  body: JSON.stringify({
    address: '0xabc123...',
    chains:  ['ethereum', 'polygon'],
  }),
});

const { data } = await res.json();
// data.watched → true
// data.chains  → ['ethereum', 'polygon']

res = requests.post(
    f"{BASE}/wallet/filter",
    headers=make_headers(),
    json={"address": "0xabc123...", "chains": ["ethereum", "polygon"]},
)
data = res.json()["data"]
