Answers:
- Providers are global API's injected by Web3 wallets into websites and Dapps at window. object (eg: window.ethereum). Provider allows websites to request users' blockchain accounts, read data from blockchains the user is connected to, and suggest that the user sign messages and transactions. At present, Near has a wallet selector to allow Near Dapps to use third-party wallets to sign transactions.

- Account modal/abstraction in near:

Near has 2 types of accounts

Implicit accounts: These are analogous to EOA accounts in Ethereum. Near uses the ED25519 algorithm for key management.

Account abstraction is achieved in Near with Explicit accounts and access keys.

Explicit accounts: These are analogous to Contract Accounts in Ethereum.
Near wallet allows the creation of explicit accounts provided there is at least 1 Near token.
Near account is not limited by pubkey/privkey, instead, accounts allow multiple access keys that can have different access levels.

Full access key: Non-limiting and is stored on browser storage in near wallet.

Function call key: Limited access, predefined gas limits, methods and contract address. It can eliminate the need to reauthorize the app every time since the key is limited to a particular contract.
