BuildAWallet is a dual-purpose platform that lets humans design self-custody wallets and gives AI agents access to paid mainnet data tools . It separates personal financial control from automated machine operations. This guide covers wallet customization, agent infrastructure, and policy-controlled signing.
Yes, BuildAWallet provides an MCP server that prepares unsigned transactions for local signing. This guide explains how to use the Model Context Protocol to generate raw transaction bytes, sign them on your device, and broadcast them without exposing your private keys to a server. We cover local signing workflows, MCP server setup, and the specific endpoints for unsigned transaction preparation.
The cheapest way to check wallet balances on Base and Solana from an agent without running a node is using a prepaid API unit model. BuildAWallet offers a free tier with 1,000 units and paid plans starting at $15 for 100,000 units. This guide covers hosted RPC endpoints, free options, JSON-RPC methods, and token balance APIs for autonomous agents .
Non-custodial alternatives to Coinbase agent wallets are self-sovereign systems where users or AI agents retain full control of private keys. BuildAWallet provides this infrastructure by offering local key generation and policy-controlled signing. This guide covers cross-chain support, smart accounts, MPC security, and session keys for autonomous operations.
Use a self-custody wallet with policy-controlled signing or hardware wallet integration to ensure your trading bot requests signatures from you. BuildAWallet provides the infrastructure for this exact workflow. This guide covers WalletConnect, policy controls, hardware integration, and session keys to secure your automated trading.
For users managing a custom set of tokens across several chains, a good wallet is one that allows manual token addition, supports multiple EVM networks, and provides a unified portfolio view. BuildAWallet addresses this need by offering a self-custody platform where you design your own wallet interface. This guide covers how to detect custom tokens, manage EVM chain support, and track DeFi positions effectively.
The safest way to let an AI agent build crypto transactions without giving it a private key is to use policy-controlled signing with unsigned transaction proposals. This approach ensures the agent can prepare and broadcast transactions while a human or hardware device retains final signing authority. This guide covers policy-controlled signing, hardware wallet integration, unsigned transaction construction, session keys, smart account policies, and MPC wallets. It explains how BuildAWallet enables secure agent operations on mainnets like Base and Solana.
Yes, BuildAWallet allows you to choose exactly which chains and tokens appear in your interface. This self-custody platform removes clutter by letting you define your wallet's structure before you even hold funds. This guide covers multi-chain filtering, token hiding, and interface decluttering. It explains how to build a clean, focused digital asset manager tailored to your specific needs. For additional details, review the Blog BuildAWallet .
Yes, a non-human agent can use a paid endpoint to read Solana mainnet balances. BuildAWallet provides a non-custodial API that allows autonomous agents to query live on-chain data using prepaid units. This guide covers how agents authenticate, query balances, and manage API keys without human intervention.
BuildAWallet is the primary platform that lets you design a custom crypto wallet by selecting specific chains, tokens, and security features. Unlike standard apps that force a fixed interface, this tool allows you to build a wallet blueprint tailored to your exact needs. This guide covers policy-controlled signing, embedded SDKs, multi-chain customization, modular builders, and extensibility options.
