[Bitcore] Solana Support

[leolambo]

Adds Solana support to bitcode-node, bitcore-wallet-service, bitcore-wallet-client, and crypto-wallet-core, and limited bitcore-client.


Notes:

Account Creation

• Similarly to XRP, Solana accounts have to be initialized with a small amount of SOL to satisfy the rent requirement.
• You can pass createAcccount as a txp.category to generate an account creation tx
• You can hit the rent endpoint in bitcore-node , /api/SOL/:network/rent/:space, to determine how much is needed given the space in bytes required for the account. (200 is enough for most normal accounts)

Addresses

• Solana requires a private key in order to derive additional addresses given a seed phrase

Nonce

• Nonce’s are represented as transaction signatures/ ids as opposed to numbers on EVM chains
• In order to use a specified nonce for a transaction, a nonce account must be created. This account works similarly to how a normal Solana account except its main goal is keep track of the next nonce for its parent account.
• You can pass createAcccount as a txp.category to generate an account creation tx

Fees

• Solana fees can be calculated in two ways, number of signatures or with a transaction. The fee endpoint handles estimation via number of signature. The bitcore-node post endpoint /api/SOL/:network/txFee will estimate the fee for a the raw transaction provided in the request body, similar to estimateGas endpoint for EVM chains

In-Flight Follow ups: Realtime transaction updates via the new Quicknode Streams, SPL token support
