-# Anker program security
-
-This document outlines our threat model and security considerations for the
-Anker program. For the general Solido security policy and how to report
-vulnerabilities, see SECURITY.md in the root of the repository.
-
-## Overview
-
-The Anker program is the Solana-side program that implements bSOL (bonded SOL)
-support for the [Anchor Protocol][anchorprotocol] on the [Terra][terra]
-blockchain. Anchor is a money market between lenders, who deposit UST
-stablecoin in return for a stable yield, and borrowers, who borrow that UST by
-putting up bonded asses such as bSOL or bETH as collateral.
-
-Bonded assets are nominally pegged to their underlying native token (so 1 bSOL =
-1 SOL), but backed by staked assets, in this case Lido’s stSOL. The Anker
-program can mint and burn bSOL, and it maintains a reserve of stSOL, such that
-for every bSOL minted, the reserve contains 1 SOL worth of stSOL. Because stSOL
-is a value-accuring token, over time the value of the reserve will be higher
-than what is needed to back the bSOL supply. To restore the peg, we swap the
-excess stSOL for UST on an AMM, and the proceeds go to the Anchor protocol on
-Terra (through [Wormhole][wormhole]), which uses them to provide the yield for
-lenders.
-
-To avoid confusion with [the Solana development framework / eDSL that is also
-called Anchor][serum-anchor], we named our program “Anker”.

-[terra]:          https://www.terra.money/
-[wormhole]:       https://wormholebridge.com/
-[serum-anchor]:   https://github.com/project-serum/anchor
-
-## Components
-
-As a cross-chain protocol, bSOL support for the Anchor protocol involves
-multiple components:
-
- * The Anker program on the Solana blockchain. This program accepts stSOL
-   deposits and mints bSOL in return, and when users return their bSOL, the
-   program burns it and returns stSOL. This means that bSOL is natively a Solana
-   SPL token, and the bSOL on Terra will be bridged. The source code of this
-   program is in the `anker` directory of <https://github.com/ChorusOne/solido>.
-
- * The bSOL contract on the Terra blockchain. For technical reasons, on the
-   Terra side the Wormhole-wrapped bSOL tokens need to be wrapped once more, and
-   this contract is responsible for that. The repository is not public while
-   the contract is being developed, but it will be analogous to the
-   existing bETH contract at
-   <https://github.com/Anchor-Protocol/anchor-bEth-contracts>.
-
- * The Anchor contract itself on the Terra blockchain.
-
- * Wormhole bridge, which is used in a few places:
-   * To get UST to Solana in the first place. (It lives natively on Terra.)
-   * To send the bSOL that users receive to Terra, so they can deposit it into
-     Anchor. This step will have to be done manually by users.
-   * To send the UST proceeds of the staking rewards to Terra.
-
- * Solido, the Lido for Solana program. The Anker program holds stSOL, which is
-   minted by Solido, and aside from that, Anker inspects the Solido state to
-   obtain the stSOL/SOL exchange rate, in order to compute bSOL/stSOL exchange
-   rate that is needed to maintain the 1 bSOL = 1 SOL peg.
-
- * An AMM for swapping stSOL for UST. We intend to use [Orca][orca] for this,
-   which is a deployment of the [SPL Token Swap][spl-token-swap] program.
-
-[orca]:           https://www.orca.so/
-[spl-token-swap]: https://github.com/solana-labs/solana-program-library/tree/master/token-swap
-
-This repository only contains the Anker program (and the Solido program), and
-only the Anker program is in scope for the purpose of auditing (and in the
-future, for the bug bounty program). The bSOL contracts on the Terra side will
-be audited separately.
-
-## Roles
-
-There are two types of actors involved in the Anker program:
-
- * **The manager**. The manager is the upgrade authority of the Anker program,
-   and it can sign configuration changes, such as the destination address for
-   UST rewards. The manager will be the same multisig instance that also acts as
-   the manager for the Solido program. We trust the manager and assume that the
-   manager acts in the best interest of the Anker program. We assume that the
-   manager will configure the Anker program correctly.
-
- * **Users**. Users deposit stSOL and receive bSOL in return.
-
-There is no separate “maintainer” role like in the Solido program. The Anker
-program is intended to be fully permissionless, and aside from configuration
-changes, there are no privileged instructions. In particular, swapping stSOL
-for UST is something that can be done by anybody.
-
-## Functionality
-
-The Anker program has three main functions for everyday use:
-
- * **Deposit**, where users deposit stSOL and receive bSOL in return.
- * **Withdraw**, where users redeem their stSOL by returning the bSOL.
- * **Claim Rewards**, where, if the value of the stSOL in the reserve is greater
-   than what is needed to back the bSOL supply at a 1 bSOL = 1 SOL exchange
-   rate, the program can swap the excess stSOL for UST against an AMM, and it
-   sends the proceeds through Wormhole to a preconfigured address on Terra.
-
-None of these functions are privileged. In practice the existing Solido
-maintainer bot is going to be responsible for calling *Claim Rewards* when
-possible. Note that, because the Solido exchange rate changes at most once per
-epoch, claiming rewards is possible at most once per epoch.
-
-## Singleton Anker instance
-
-We follow Neodyme’s recommendation about making the Anker instance a singleton,
-with one modification: because Solido is not (enforced to be) a singleton, we
-have one Anker instance per Solido instance. The Anker instance lives at a
-program-derived address that is derived from the Solido instance’s address. This
-ensures that there is one unique Anker instance associated with every Solido
-instance.
-
-## Scope and trust
-
-For auditing, and a future bug bounty, the scope is limited to the Anker program
-and its responsibilities. Examples of issues we would like to know about:
-
- * Minting bSOL without providing the backing stSOL of the right value.
- * Withdrawing stSOL without returning any bSOL of the right value.
- * Preventing future deposits or withdrawals.
- * Changing configuration without signature from the manager.
- * Sending UST proceeds to a different recipient than the address configured in
-   the Anker instance.
-
-Once we mint the bSOL, what happens to it (either on Solana or on Terra) is no
-longer the concern of the Anker program. Examples of issues out of scope:
-
- * Vulnerabilities in the bSOL contract on the Terra side (it will be audited
-   separately).
- * Attacks that involve manipulating Wormhole.
-
-The Anker program necessarily interacts with other programs, and those programs
-are upgradeable. Therefore:
-
- * We trust the Orca Swap program and its upgrade authority.
- * We trust the Wormhole program and its authority.
-
-We are interested in minimizing the impact that a compromised Orca or Wormhole
-program could have, but in principle we trust these programs.
-
-We also trust the contracts on the Terra side that we send the UST rewards to.
