This endpoint is designed for users to start earning interest or to use their deposited collateral for borrowing. Gas optimization settings ensure that the deposit transaction is both efficient and cost‐effective. > 💡 **Compute Unit Value:** `230` (Fixed) # OpenAPI definition ```json { "openapi": "3.0.0", "info": { "contact": { "name": "Blockdaemon", "email": "info@blockdaemon.com" }, "description": "The Blockdaemon DeFi API provides a single interface to a multitude of DeFi projects and blockchains", "title": "Blockdaemon DeFi API", "version": "1.0.0", "x-logo": { "altText": "Blockdaemon logo", "backgroundColor": "#fafafa", "url": "https://storage.googleapis.com/blockdaemon-app-static-images/marketing/PNG/dark-logo.png" } }, "externalDocs": { "description": "Blockdaemon DeFi documentation", "url": "http://www.blockdaemon.com/api/defi" }, "servers": [ { "url": "https://svc.blockdaemon.com" } ], "components": { "securitySchemes": { "ApiKeyAuth": { "type": "apiKey", "in": "header", "name": "X-API-Key", "description": "`X-API-Key: ` header must be set to authenticate API requests.You can create tokens in the \"Configure\" tab of your API access area at https://app.blockdaemon.com." } }, "schemas": { "_lendborrow_deposit_Request": { "type": "object", "properties": { "lendborrowId": { "type": "string", "description": "The unique ID to specify the lending and borrowing protocol for routing relevant queries or transactions.", "enum": [ "1000", "1003", "1005", "1200", "1208", "1203", "1204", "1205", "1206", "1207", "1100", "1300", "1302", "1400", "1401", "1402", "1403", "1404" ], "example": "1000" }, "asset": { "type": "string", "description": "Token address of the asset to deposit.", "example": "0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2" }, "amount": { "type": "string", "description": "Number of tokens, specified in the token's smallest denomination (base units).
