Overview

The wallet service and blockchain node provider service, all bundled into one.

What is Layer1

Layer1 is a self-hosted digital asset platform built for modern payment and treasury infrastructure. It abstracts away the complexity of interacting with multiple blockchains, so you can secure keys, process transactions, and manage assets — all within your own environment.

Designed by veterans of payment platforms, Layer1 helps you integrate faster and launch faster, with robust tooling and modular components for custody, trading, compliance, and more.

With Layer1, you can:

• Enable 24/7, real-time payments across multiple blockchain networks.
• Support 10+ major cryptocurrencies out of the box.
• Build tailored digital asset workflows for your business.
• Customize custody models based on your risk profile.
• Manage your own crypto treasury.
• Launch revenue-sharing models with minimal engineering effort.

Why Teams Choose Layer1

• Minimal blockchain expertise required. Integrate without needing to know chains, gas, or token standards.
• Automated fund flows. Withdrawals are automatically routed and consolidated.
• Plug-and-play compliance. Just connect your provider — no extra dev work.
• No ongoing engineering burden. Layer1 is maintained for you; your team stays lean.
• Smart treasury management. Trade and move assets across venues easily.
• Simple asset conversion. Use a single API to convert between supported assets — including synthetic pairs.

Layer1 Core Systems

Your Layer1 account gives you access to a suite of composable services via a single, unified API:

• Layer1 Vault.
  A self-hosted key management system (KMS) that secures private keys inside your infrastructure. Built with best-in-class security standards for digital asset custody.
• Digital Asset Services.
  A blockchain abstraction layer that simplifies cross-chain operations. Automatically consolidates funds, routes withdrawals, and calculates optimal fees across networks and tokens.
• Trading Service.
  Route and execute trades across multiple venues through one integration. The Layer1 trade router finds the best price and execution path — including synthetic pairs — without manual strategy setup.
• Transaction Screening.
  Plug in your compliance provider credentials to enable automatic transaction screening. Manage flagged transactions through an integrated dashboard — no extra development needed.
• User Interface.
  A clean, white-labeled interface that gives your team (or customers) access to all Layer1 features without writing code.

Conceptual Model

The Layer1 platform is a multi-tenant solution. A single tenant can create as many distinct asset pools as required.

Four main components function within Layer1 creation:

• Asset Pool:
  An asset pool represents a collection of funds across different currencies and networks. By grouping these funds together, the complexity of managing multiple crypto addresses and key pairs is hidden from the customer, enabling them to focus on actions at the pool level rather than individual addresses. The asset pool simplifies fund management by abstracting away network-specific details, providing a unified interface for handling diverse crypto assets.
• KeyPair:
  A key pair is the cryptographic foundation of blockchain transactions. It consists of a public and a private keys. The key pair secures access to blockchain addresses and ensures that only authorised transactions can be conducted. Public-private key cryptography is integral to verifying transactions and securing assets on the blockchain.
  Multiple key pairs can be created within a single asset pool. A key pair is used to create an address on any of the supported blockchain networks.
  A single key pair can be used to create a unique blockchain address on any of the supported networks. Each network address must be distinct and cannot be duplicated. For instance, a single key pair cannot generate multiple Ethereum addresses. However, the same key pair can be used to create different blockchain addresses on various networks such as Ethereum, Bitcoin, Tron, etc.
• Address:
  An address is a unique identifier on a specific blockchain network where assets can be sent or received. It is generated using the public key from the key pair and serves as the "account number" for blockchain transactions.
  When the blockchain network allows it, a single address can support multiple assets. For example, a single Ethereum address can hold ETH, USDT, and USDC assets.
• Asset:
  An asset is the value held in a specific currency that can be transferred on the blockchain. Assets are units that move between addresses and are accounted for within an asset pool.
