Chronicle’s VAO dashboard is the first transparency layer for oracles and tokenized RWAs, giving institutions, builders, and policymakers easy-to-access visibility into how asset data is sourced, verified, and monitored onchain.
Chronicle Oracles have launched on Avalanche. Developers can access 140+ resilient, robust data models for crypto and tokenized assets.

63+ Oracle data feeds, including asset prices, yield rates, and more, arrive on BASE, unlocking the first fully verifiable, transparent, and gas-efficient option for DeFi.
The secret weapon behind this revolutionary new Oracle offering is Scribe, the groundbreaking Schnorr signature-based architecture that delivers unique efficiency, security, and transparency upgrades for Oracle users. More on Schnorr later.
We’ve launched three new price feed Oracles: cbETH/USD, cbETH/ETH, and cbETH/USDC, which are now available on BASE and across the EVM. DeFi builders can now utilize Coinbase Wrapped Staked ETH (cbETH) using the longest-running and most secure Oracle network available.
Powered by the OP Stack, BASE is a secure, low-cost, builder-friendly Ethereum L2 with an ambitious goal of bringing the next billion users on-chain. Empowered by the popular CEX, Coinbase, BASE already boasts a fast-growing DeFi ecosystem, and we’re delighted to be able to bring the Oracle network powering ~20% of DeFi on Ethereum, including MakerDAO, Spark, and more, to the chain.
Low gas fees are a key component of BASE, and this mission aligns perfectly with Chronicle’s Scribe Oracle, which is the first Oracle to tackle the inherently high gas cost of operating Oracle networks. The result is an Oracle that costs up to 6x less than Chainlink to update and 3.5x less than Pyth (on L1 and L2). This was achieved using Schnorr signatures - to read more about that, check out this research report by Token Terminal.
With Scribe's arrival on BASE, builders will immediately gain access to these huge cost-saving benefits without having to compromise on the security, resilience, or decentralization of the Oracle network.

The TL;DR on Scribe
Choosing an Oracle to secure your protocol and its TVL is the most important consideration of them all. With that in mind, we’ve prepared a short rundown of the questions every Oracle user should have definitive, verifiable answers to and how Scribe stacks up:
Where does the data come from?
Chronicle Scribe displays every data source in real-time and historically via The Chronicle, our on-chain dashboard. Pick an Oracle, choose a time and date on the graph, and hit the drop-down arrow on any validator to see which exchanges they queried for the price data.
wstETH/USD Oracle sources & values
Oracle providers that use low volume and low liquidity exchanges or liquidity pools for data sources are the reason behind most DeFi protocol attacks. Every Oracle protocol should provide complete data source transparency to their users, and in a cryptographically verifiable way - not just words and images. Don’t trust, verify.

How many validators or signers does the protocol have?
At Chronicle, we refer to these protocol actors as validators. By other providers, they are sometimes referred to as signers or Oracles. Essentially, these are the actors that operate the nodes on the protocol that attest (or sign) to the integrity of the reported data (such as the price of BTC/USD at a specific time).
This is how to establish truth in an Oracle network. Enough of these nodes must report back with the requested data to develop a consensus. However, if a bad actor can gain control of the majority of these nodes, they can manipulate the reported data. Therefore, the more validators or nodes an Oracle protocol has and the more distributed (or decentralized) they are, the more secure it is from being hacked.
Using The Chronicle, anyone can see who Chronicle Protocol’s validators are, which cryptocurrency pairs or Oracles they are sourcing data for, and when their reported data was last updated.
Scribe is the first Oracle design to pioneer the use of Schnorr signatures. This allows Chronicle Protocol to scale to an unlimited number of validators. No other Oracle protocol can achieve this as they all use an implementation of ECDSA that has a linear relationship between the number of validators and the cost of operating the Oracle.
Oracle networks constructed in this way must keep validator or signer numbers low to maintain a lower operating cost, sacrificing better security and decentralization.

Who are the protocol validators or signers
Knowing the identity of the validators is just as important as the total number. This is because an actor running a node can report any data they please. For example, they could have the node report that BTC is worth $10,000 when the market value is $40,000, creating an attack vector and draining the DeFi protocol the Oracle ‘secures.’
Therefore, decentralized and distributed nodes should be at the top of your Oracle provider shopping list unless you want your Oracle provider to have the power to drain your project. Right now, more than one Oracle provider runs all or the majority of its protocol’s nodes themselves, securing millions of dollars of TVL. Nothing stops them from draining your project if they get compromised. This is the risk of using a centralized Oracle.
At Chronicle, all of our validators are distributed and identifiable, and many are operated by well-known brands with a good reputation and track record—projects such as MakerDAO, Infura, Gnosis, Gitcoin, Etherscan, and DeFi Saver. Our goal is to create a validator community of some of the most used protocols in the space, creating a positive feedback loop of increasing security and decentralization.

What does it cost to operate the Oracles?
Oracles are very gas-hungry. For example, every time the BTC/USD Oracle (or Feed) updates to the latest price, this has a gas cost as it is required to post the result on-chain. Regardless of L1 or L2, the more updates, the more cost, and the Oracle provider shoulders that cost. Therefore, many Oracle providers look to update the data less frequently. This creates stale data and opens up opportunities for arbitrage, with both the Dapp and the user of the Dapp losing out.
With Scribe, we have tackled the underlying engineering problem behind the high cost of operating Oracles. The result is an Oracle that costs up to 6x less than Chainlink to update and 3.5x less than Pyth (on L1 and L2). This was achieved using Schnorr signatures - to read more about that, check out this research report by Token Terminal.
About Chronicle Protocol
Chronicle Protocol is a novel Oracle solution that has exclusively secured over $10B in assets for MakerDAO and its ecosystem since 2017. With a history of innovation, including the invention of the first Oracle on Ethereum, Chronicle Protocol continues to redefine Oracle networks. A blockchain-agnostic protocol, Chronicle overcomes the current limitations of transferring data on-chain by developing the first truly scalable, cost-efficient, decentralized, and verifiable Oracles, rewriting the rulebook on data transparency and accessibility.
Base is a secure, low-cost, builder-friendly Ethereum L2 built to bring the next billion users onchain.
Base is incubated within Coinbase and plans to progressively decentralize in the years ahead. We believe that decentralization is critical to creating an open, global cryptoeconomy that is accessible to everyone.
