# Standard contracts overview (https://docs-rbcpr9qys-ton-core-docs.vercel.app/llms/standard/overview/content.md)



This section lists the most popular standardized contracts and describes how to work with them without developing new ones. For the latter, see [Contract development](https://docs-rbcpr9qys-ton-core-docs.vercel.app/llms/contract-dev/overview/content.md).

## Wallets [#wallets]

On TON, [wallets are smart contracts](https://docs-rbcpr9qys-ton-core-docs.vercel.app/llms/standard/wallets/how-it-works/content.md) that operate under the same rules as any other contract on the blockchain. Their distinctive feature is to act as a proxy: wallets handle an external message sent from off-chain, verify that the message was sent by the wallet's owner using public-key cryptography, and send an internal message somewhere further on-chain.

## Tokens [#tokens]

TON blockchain supports three distinct categories of digital tokens: [Jettons](https://docs-rbcpr9qys-ton-core-docs.vercel.app/llms/standard/tokens/jettons/overview/content.md), [NFTs](https://docs-rbcpr9qys-ton-core-docs.vercel.app/llms/standard/tokens/nft/overview/content.md), and [SBTs](https://docs-rbcpr9qys-ton-core-docs.vercel.app/llms/standard/tokens/jettons/overview/content.md). All of them utilize the single [metadata standard](https://docs-rbcpr9qys-ton-core-docs.vercel.app/llms/standard/tokens/metadata/content.md).
