Anchor Protocol allows Terra stablecoin deposits to earn stable yield, powered by block rewards of leading proof-of-stake blockchains. Terra stablecoins offer instant settlements, low fees and seamless cross-border exchange - loved by millions of users and merchants. Mirror Protocol allows the creation of fungible assets, “synthetics”, that track the price of real world assets. Mirror synthetics are intended to be used as key building blocks in smart contracts, and to bring the world’s assets to the blockchain. Build smart contracts in Rust, Go, or AssemblyScript. Run on multiple chains, connected by the Cosmos IBC. Use Terra stablecoins, onchain swaps, layer 1 oracles as primitives. Expose dApp userbases to Terra's payment services in a permissionless fashion. Terra aims to make its stablecoins available to every developer on every blockchain. Now live on Ethereum and Solana, and coming to more soon.

Qtum is an open-sourced public blockchain platform, leveraging the security of UTXO while enabling multiple virtual machines including EVM. Qtum is PoS based and boasts a Decentralized Governance Protocol (DGP) allowing specific blockchain settings to be modified by making use of smart contracts. For instance, the block size of Qtum can be increased without the need for a hard fork. Qtum provides a standardized, stable, and safe development environment for smart contracts, enabling business-friendly smart contract coding, deploying, and executing. Qtum is also a decentralized application platform, compatible with existing blockchain infrastructure, and is modularized so new technology can always be added. There is a full spectrum of crypto wallets supporting Qtum, that meet the needs of different users. Qtum also provides mature development resources for blockchain and app development.
