#1 by TVSPush + PullToken: LINKSince 2019
The industry-standard oracle network — secures the most value in DeFi by a wide margin.
- Type
- Push + Pull
- How it works
- Decentralized Oracle Networks (DONs); heartbeat + deviation threshold. Data Streams add a low-latency pull mode.
- Chains
- 40+ — Ethereum + every major L1 and L2 (Arbitrum, Optimism, Base, zkSync, Polygon, Avalanche…).
- Feeds
- 1,000+ — Price feeds across crypto, FX, commodities + Proof of Reserve.
- Security
- Many independent, Sybil-resistant node operators per DON, with LINK staking and reputation.
- TVS*
- ~$33B (≈59%)
- Token
- LINK
- Notable users
- Aave, Compound, Sky (Maker), Synthetix, GMX, Lido
* Approximate total value secured — a dated market snapshot (DefiLlama / provider reports, 2026), not a live figure.
Best at
Broadest coverage + a full stack: CCIP cross-chain, VRF randomness, Functions, Proof of Reserve, Data Streams.
Native on Ethereum and every major L2 — the default choice for blue-chip lending and stablecoins.
Strengths
- Most battle-tested and widely integrated
- Widest chain + feed coverage
- Full product suite beyond price (CCIP, VRF, PoR)
- Deepest decentralization & staking security
Trade-offs
- Push feeds cost on-chain gas to maintain
- Standard feeds less granular than pull for HFT-style use
- Premium positioning
