List of Custody Technology Provider projects on Arbitrum (2026)

Fireblocks Wallets is a custody technology platform providing MPC-based wallet infrastructure for institutional digital asset operations. The platform uses multi-party computation to distribute private key control across multiple parties, eliminating single points of failure in key management. A configurable policy engine enforces transaction authorization rules, enabling treasury management, DeFi access, and compliance workflows across multiple blockchains.

Fireblocks Off Exchange is a settlement service that allows trading firms to keep collateral in Fireblocks-secured custody while trading on partner exchanges, rather than depositing funds directly onto exchange accounts. Positions and margin are tracked and settled between the custodied wallet and the exchange without moving assets onto the exchange itself. The service reduces counterparty exposure to exchanges for institutional trading operations.

Safe{API} is developer infrastructure for building applications on Safe smart accounts. It provides APIs and SDKs for managing transactions, monitoring wallet activity, and automating transaction proposals and workflows.

Safeheron MPC Self-Custody is an institutional self-custody platform that uses multi-party computation and trusted execution environment technology to remove single points of failure while keeping full private key control. It provides multi-chain wallet governance through an Asset Vault and DeFi Vault, a configurable policy engine for transaction approvals, and compliance monitoring against high-risk transactions. Institutions access the platform through a mobile application, web console, browser extension, or APIs and SDKs to manage digital assets and connect securely to decentralized applications.

Alchemy Account Kit provides account abstraction infrastructure, including smart account contracts, SDK components, bundler services, and gas sponsorship, for gasless transactions and social login. Signer integrations support embedded wallet experiences.

Cregis Wallet as a Service is an enterprise infrastructure product that lets businesses generate wallet addresses and manage crypto transactions through an API without building custody technology themselves. It provides white-label wallet functionality that companies can embed into their own products, with addresses owned by the business. The service supports multi-chain asset operations and hosted front-end components for faster integration.

SINOHOPE Custody Platform provides institutional wallet and custody services in two modes. The MPC wallet splits private key control across several parties for self-custody, while the full custody wallet offers a managed custodial setup. Both include approval workflows, role-based permissions, and compliance monitoring, and APIs let developers integrate wallet functions into their own applications.

io.vault is a self-custody wallet for institutions and teams that uses multi-party computation so no single party controls the keys. Users approve transactions from a dashboard, API, or mobile app, apply transaction policies, and connect to DeFi protocols with simulated results before signing. It automatically supports tokens issued on its supported networks.

Uniwire Payment Gateway is a cryptocurrency payment processor that lets businesses accept, convert, and pay out digital assets through a dashboard, REST API, JavaScript SDK, or WooCommerce plugin. It generates invoices, processes multi-chain deposits, and executes automatic crypto-to-crypto conversion and withdrawals to blockchain addresses or bank accounts based on configurable thresholds. The system provisions MPC-based wallets for each merchant, supports Bitcoin transaction processing without waiting for confirmations, and integrates the Lightning Network's LNURL protocol alongside connections to third-party exchanges and on/off-ramp providers.

A TypeScript library built on Viem that provides a unified interface for building chain-abstracted smart accounts (Omni Accounts). The SDK supports account-agnostic development, intent creation, multi-chain abstraction, and module customization with familiar APIs.

Nexus is a modular smart account platform that replaces traditional externally owned wallets with programmable, ERC-4337 and ERC-7579 compliant accounts. It provides custom authentication, session-based permissioning, and gas abstraction so applications can sponsor fees or let users pay gas in any token. Built-in smart sessions let users delegate scoped, revocable permissions to bots or AI agents with spending limits and contract whitelists, enabling automated onchain actions without exposing full account control. The account is compatible with EIP-7702, allowing existing wallets to gain smart account capabilities, and deploys with unified addresses across multiple blockchains.

Cobo Portal is a digital asset wallet platform that lets institutions manage custody, trading, and treasury operations from one interface. It combines custodial, multi-party computation, smart contract, and exchange wallet technologies under unified risk controls, approval workflows, and portfolio dashboards. Users connect to decentralized applications and centralized exchanges directly from the platform while enforcing customizable transaction and governance policies.

August is an onchain prime brokerage platform that gives institutions infrastructure to manage and settle digital assets. It combines smart contract accounts, pricing and risk engines, and execution tools so institutions can borrow, lend, and trade across DeFi, spot, and OTC markets. It also serves as the custody layer that other protocols, including Upshift, build on.

Bitpowr is a digital asset custody and wallet infrastructure platform for institutions and developers. It secures keys with multi-party computation and hardware security modules and offers a policy engine, tokenization, and compliance tools including AML and KYT monitoring. Businesses use it to create and manage wallets across multiple blockchains.

Utila Platform is an institutional MPC wallet platform for managing stablecoins and other digital assets. It protects keys with multi-party computation and enforces roles, limits, approval workflows, and address whitelists before any transaction executes. Teams use it for custody, treasury management, trading operations, and business continuity across a wide range of blockchains. It connects to exchanges, liquidity venues, on-ramps and off-ramps, and compliance providers through built-in integrations and a partner network. REST APIs and webhooks let developers automate wallet and transaction workflows.

Wallet Builder lets enterprises create white-label wallets for mobile and browser extensions without writing code. Wallets include phone and email login, DApp connectivity, and push notifications, with SDK and API access for deeper integration. Enterprises can view user activity in KryptoGO Studio.
