Base

tip

Available for Freemium and Premium users.

Base API is available on Web3 API platform.

Base is a secure, low-cost, developer-friendly Ethereum L2 built to bring the next billion users to web3.

Base is built on the Bedrock release of the OP Stack, which is designed from the ground up to be as close to Ethereum as possible. Because of this, there are very little differences when it comes to building on Base and Ethereum.

However, there are still some minor discrepancies between the behavior of Base and Ethereum that you should be aware of when building apps on top of Base.

These minor differences include:

BNB Smart Chain

tip

Available for Freemium and Premium users.

BNB Smart Chain API is available on Web3 API platform.

BNB Smart Chain (BSC) (previously Binance Smart Chain) is an innovative solution to bring programmability and interoperability to Beacon Chain. BNB Smart Chain relies on a system of 21 active validators with Proof of Staked Authority (PoSA) consensus that can support short block time and lower fees. The most bonded validator candidates of staking will become validators and produce blocks. The double-sign detection and other slashing logic guarantee security, stability, and chain finality.

To the EVM compatibility that permits support for Ethereum tools and DApps, BNB Smart Chain adds smart contract functionality to the chain. The dual-chain architecture alongside Binance Chain enables sending and receiving of BNB and BEP2 tokens cross-chain.

Add networks to MetaMask

Using Ankr as the blockchain provider for MetaMask makes user interaction on Web3 not just easy and slick but also PRIVATE. We DON'T collect users' blockchain addresses — end of the story. Feel free to check our terms and privacy policy to be sure.

For MetaMask to interact with BNB Smart Chain through Ankr's infrastructure, add a required BNB Smart Chain network either via Web3 API platform's or MetaMask's UI.

Via Web3 API platform

To be added soon.

Via MetaMask

To add BNB Smart Chain Mainnet, follow these steps:

In MetaMask extension, click Networks (drop-down menu) > Add network to open Settings.
In the Add a network pane, click Add a network manually, then enter the network details and click Save:
- Network name: BNB Smart Chain Mainnet by Ankr RPC.
- New RPC URL: https://rpc.ankr.com/bsc/{your_token}.
- Chain ID: 56.
- Currency symbol: BNB.
- Block explorer URL: https://bscscan.com/.

Congrats — you've just added Ankr as the blockchain provider for MetaMask to interact with BNB Smart Chain Mainnet.

To add BNB Smart Chain Testnet, follow these steps:

In MetaMask extension, click Networks (drop-down menu) > Add network to open Settings.
In the Add a network pane, click Add a network manually, then enter the network details and click Save:
- Network name: BNB Smart Chain Chapel Testnet by Ankr RPC.
- New RPC URL: https://rpc.ankr.com/bsc_testnet_chapel/{your_token}.
- Chain ID: 97.
- Currency symbol: BNB.
- Block explorer URL: https://testnet.bscscan.com/.

Congrats — you've just added Ankr as the blockchain provider for MetaMask to interact with BNB Smart Chain Chapel Testnet.

Botanix

Botanix API is available on Web3 API platform.

Botanix is a decentralized Turing-complete Layer 2 EVM built on the native currency of bitcoin. It operates using two core components:

Ethereum Virtual Machine: Fortified by a Proof-of-Stake consensus protocol that leverages Bitcoin's Proof-of-Work for superior security. Stakes are represented by actual bitcoin stored securely within multi-signature wallets on the Bitcoin network. By supporting EVM, Botanix allows developers to seamlessly port existing Ethereum dApps to the Bitcoin ecosystem.
Spiderchain Protocol: At the core of Botanix is the Spiderchain, a series of successive multisignature (multisig) wallets managed by randomized sets of orchestrators. This structure secures user funds and facilitates the movement of Bitcoin within the network, effectively separating Bitcoin "the asset" from Bitcoin "the blockchain." By securing the Bitcoin present on Botanix in a decentralized chain of multisigs, it separates Bitcoin from the EVM. This allows for a transition from Bitcoin’s UTXO model to an account model used in the EVM.
