TEAL ALGO Oracle in Algorand Layer-1

In a blockchain, the ability to reference a price on-chain enables a seamless and trustless transaction environment, especially for automated transactions and smart contracts. Oracles are the entities in charge of broadcasting off-chain data such as market price to the blockchain, and serve as a source of truth that allows on-chain dApps to measure the value of assets referenced within a transaction. Rand Labs and Borderless Capital releases a Algorand Oracle that can be referenced in atomic transfers using TEAL stateful and stateless smart contracts.
