# Chains Overview

Dynamic organizes chain support into three tiers based on the depth of embedded wallet integration.

***

## Tier 1 — Native Embedded Wallets

Native embedded wallets with gas abstraction, policies, and enhanced abstractions. Wallet creation, UI components, transaction signing, and chain-switching work out of the box — no custom code required.

**Tier 1 chains:** Ethereum (+ all EVM networks), Solana, Bitcoin, Sui, TON, Stellar, Tempo, Arc.

→ See [Getting Started guides](/docs/overview/introduction/welcome#using-documentation) to integrate any Tier 1 chain.

***

## Tier 2 — Embedded Wallets via Raw Signing

Embedded wallets via raw signing with helper methods and EOA support. Gas handling and policies are not yet supported.

Because many blockchains share the same elliptic curves (`secp256k1` and `Ed25519`), a single Dynamic embedded wallet can produce valid addresses and signatures across multiple chains — no additional keys or user sign-ups required. Dynamic provides helper functions and example code for all Tier 2 chains.

**From the Solana embedded wallet (Ed25519):** Aptos, Algorand

**From the EVM embedded wallet (secp256k1):** Cosmos SDK chains, Tron

**From the Bitcoin embedded wallet (BIP-340):** Spark

→ See [chains with Tier 2 support](/docs/overview/wallets-and-chains/chains) for implementation details and helper functions.

***

## Tier 3 — Embedded Wallet Derivation Only

Embedded wallet derivation only. The same signing primitives apply, but Dynamic does not provide official helper functions or example code.

**From the Solana embedded wallet (Ed25519):** NEAR, Cardano, Mavryk

**From the EVM embedded wallet (secp256k1):** XRP, and any other secp256k1 chain

→ See [chains with Tier 3 support](/docs/overview/wallets-and-chains/tier-3-chains) for guidance on implementing support for unlisted chains.

## External Wallet Support

Dynamic supports connecting externally-managed wallets via the following standards:

* WalletConnect
* ERC-6963
* Mobile Wallet Protocol
* Smart Wallets (ERC-1271 and ERC-6492)
* Solana Wallet Standard
* Bitcoin Wallet Standard
* Sats Connect
* Spark Wallet
* Custom Wallet Connectors

→ See [External Wallets](/docs/overview/wallets-and-chains/wallets) to connect or bring your own wallet.
