# Supported Blockchains and Assets

OffBlocks is built in a chain-agnostic way and we're striving to support all major blockchains with smart contract and account abstraction support. Nevertheless, we are adding support for new blockchains in a staged approach with major EVM-based blockchains leading the way.

When it comes to assets available to fund payments, we are striving to support as many tokens as we can, with initial emphasis being on natively supported stablecoins such as USDC and EURC.

Please, refer to the following tables for latest status on all supported blockchains and assets.
