Additional tools include Ledger Recover for wallet restoration, integration with over 50 software wallets, and staking for ETH, SOL, ATOM, and ADA, ensuring user control and accessibility.
Chainlink is the leading oracle platform powering DeFi and onchain capital markets, securing over $25 trillion in transaction value by delivering reliable data, identity, compliance, and connectivity across blockchains and legacy systems. Core services include secure oracles for price feeds and data delivery in protocols like Aave and Lido, the Cross-Chain Interoperability Protocol (CCIP) for seamless multi-chain settlements and tokenized assets, and support for compliant stablecoins with transparency and auditability. Trusted by institutions such as Swift, Mastercard, and UBS, it enables scalable, verifiable infrastructure for financial innovation in Web3.
Celestia is the first modular data availability network, introducing a new paradigm in blockchain architecture by separating the consensus and data availability layers from execution. Rather than processing transactions itself, Celestia provides a scalable data availability layer that other blockchains (rollups) can use to publish and verify their transaction data. This modular approach allows rollup developers to deploy sovereign chains with their own execution environments while relying on Celestia for secure, scalable data availability. The network uses Data Availability Sampling (DAS), which allows light nodes to verify data availability without downloading entire blocks, enabling the network to scale as more light nodes join. Celestia's Blobstream bridges data availability attestations to Ethereum and other chains. The project was co-founded by Mustafa Al-Bassam and has become foundational infrastructure for the modular blockchain thesis.
LayerZero is an omnichain interoperability protocol that enables cross-chain messaging and asset transfers between different blockchains. Rather than operating bridges with locked liquidity, LayerZero provides a messaging layer that allows smart contracts on one chain to communicate directly with contracts on another chain through a system of ultra-light nodes, oracles, and relayers. The protocol supports over 50 blockchains including Ethereum, BNB Chain, Avalanche, Polygon, Arbitrum, Optimism, and Solana. LayerZero powers several major cross-chain applications including Stargate Finance for token transfers, and enables developers to build omnichain fungible tokens (OFTs) and NFTs that exist natively across multiple chains.
Ondo Finance is a real-world asset (RWA) tokenization platform that brings institutional-grade financial products on-chain. Its flagship products include USDY, a tokenized note backed by U.S. Treasuries and bank deposits that offers yield to non-US holders, and OUSG, a tokenized short-term U.S. Treasury fund. Launched in 2022, Ondo bridges traditional finance and DeFi by making regulated, yield-bearing assets accessible on multiple blockchains including Ethereum, Solana, and Mantle. The protocol partners with major institutions like BlackRock for underlying assets and has become one of the largest RWA protocols by TVL.
Starknet is an Ethereum Layer 2 scaling network developed by StarkWare that uses STARK (Scalable Transparent ARgument of Knowledge) validity proofs to achieve massive transaction throughput. Unlike EVM-compatible rollups, Starknet uses its own virtual machine (Cairo VM) and the Cairo programming language, offering computational advantages for complex operations. The network supports account abstraction natively, enabling advanced wallet features and flexible transaction signing. Starknet has attracted a significant developer ecosystem building DeFi protocols, gaming applications, and infrastructure tools, with a focus on enabling applications that would be prohibitively expensive on Ethereum mainnet.
Injective is a Layer 1 blockchain built specifically for finance, offering a fully decentralized, interoperable, and highly performant infrastructure for DeFi applications. Built on the Cosmos SDK with IBC (Inter-Blockchain Communication) support, Injective provides a plug-and-play financial infrastructure that includes a built-in on-chain order book, binary options, prediction markets, and derivatives capabilities. The chain features zero gas fees for end users (fees are handled differently through a burn auction mechanism), making it uniquely positioned for high-frequency trading and financial applications. Injective supports CosmWasm smart contracts and has introduced inEVM for Ethereum compatibility. The network uses Tendermint-based instant finality consensus and achieves block times under one second. The ecosystem spans derivatives exchanges, spot DEXes, lending protocols, and RWA platforms.
Wormhole is a cross-chain messaging and bridging protocol that connects over 30 blockchains, enabling the transfer of assets and data between different networks. Originally built on Solana, Wormhole has expanded to support Ethereum, BNB Chain, Polygon, Avalanche, Arbitrum, Optimism, Sui, Aptos, and many other chains. The protocol uses a network of Guardian nodes that observe and validate cross-chain messages, with 19 validators securing the network. Wormhole supports various cross-chain use cases including token bridges, NFT transfers, cross-chain governance, and generalized message passing. It is one of the most widely adopted bridge protocols, securing billions in cross-chain transfers.
