LTC-20 is presented as a token standard associated with the Litecoin project, intended to provide a fungible token interface analogous to ERC-20 on Ethereum. Although the specific GitHub repository at https://github.com/litecoin-project/ltc-20 currently returns a “Page not found” (404) on GitHub, the name implies a specification for minting, transferring, and managing tokens within the Litecoin ecosystem or compatible layers. The standard likely targets interoperability, simple transfer and allowance mechanics, and integration with wallets and explorers while remaining lightweight and aligned with Litecoin’s design principles. Because the original repository is unavailable, developers and integrators should seek official Litecoin Project channels, archived copies, or other authoritative sources before implementing or relying on the standard in production.

The SRC-20 token standard is a fungible token specification emerging within the Stacks and Bitcoin ecosystem that enables developers to issue, transfer, and manage tokenized assets anchored to Bitcoin through the Stacks network. SRC-20 defines a straightforward set of on-chain behaviors for minting, transferring, and querying balances while enabling interoperability across wallets, marketplaces, and DeFi rails built on Stacks. Trust Machines — a company focused on Bitcoin staking, DeFi, and developer tooling — documents and educates the community about SRC-20 to promote secure, composable token usage on Bitcoin-enabled smart contract platforms. The standard opens practical paths for stablecoins, governance tokens, community currencies, and tokenized assets while emphasizing on-chain provenance and censorship resistance derived from Bitcoin’s settlement model. As adoption grows, SRC-20 tooling, wallets, and marketplaces are evolving to support developer workflows, user experience, and integration into broader Bitcoin-first decentralized finance.

The Nirvana Upgrade for ORC-20 represents a coordinated protocol migration and enhancement designed to modernize ORC-20 token inscription formats, improve interoperability, and prepare the ecosystem for broader DeFi use on Bitcoin Ordinals. The upgrade includes a snapshot at block height #818418 and a Genesis Launch at #818419, requiring indexers and minting services to update their support to reflect migrated balances. Key changes include streamlined inscription fields, stablecoin support (e.g., USDT and USDC), a transfer model aligned with BRC-20, and the addition of native OTC atomic swap capabilities and an ORDER-BOOK for AMM-like functionality. The update also shifts reward mechanisms toward decentralization, clarifies indexing rules, and fixes multiple bugs, all to encourage developer participation and wider on-chain utility.
