BTC Collateralization Through Flow API

btc-collateralization.md

Create the collateral:

const headers = { Authorization: MY_COMPANY_API_KEY };
const data = {
  where: {},
  data: {
    fee: 100,
    borrower: {
      cardinal: {
        amount: 100,
        value: item.address,
        publicKey: item.pubkey.toString("hex"),
      },
    },
    expiry: moment().add(1, "d").format(),
  },
};

const { data: escrow } = await axios.post(
  `${DEEP_LAKE_REST_API_URL}/flows/execute`,
  data,
  { headers }
);

Sign and broadcast the collateral:

const headers = { Authorization: MY_COMPANY_API_KEY };
const data = {
  where: { id: flow.id },
  data: {
    state: "broadcast-lock",
    transactions,
  },
};

const { data: escrow } = await axios.post(
  `${DEEP_LAKE_REST_API_URL}/flows/execute`,
  data,
  { headers }
);

Unlock the collateral:

const headers = { Authorization: MY_COMPANY_API_KEY };
const data = {
  where: { id: flow.id },
  data: {
    state: "unlock",
    fee: 200,
    index: 0,
  },
};

const { data: escrow } = await axios.post(
  `${DEEP_LAKE_REST_API_URL}/flows/execute`,
  data,
  { headers }
);

Sign and broadcast the unlock:

const headers = { Authorization: MY_COMPANY_API_KEY };
const data = {
  where: { id: flow.id },
  data: {
    state: "broadcast-unlock",
    transactions,
  },
};

const { data: escrow } = await axios.post(
  `${DEEP_LAKE_REST_API_URL}/flows/execute`,
  data,
  { headers }
);

The flow API uses these APIs under the hood:

Escrow:

• Create Escrow
• Execute Escrow
• Broadcast Escrow
• Collateral API
• Asset API
• Action API

Outcomes:

• Create Outcomes and integration with the oracle
• Check one Outcome

Signatures:

• Execute signature

Logs:

• Audit trails
