What Solidity protocols and architecture standards are used?

Plain English Summary

GhostCap contracts are written in modern Solidity 0.8.24 and deployed on Base (an Ethereum Layer 2 network). Each company gets a lightweight, ultra-secure digital twin that inherits shared protocol upgrades instantly while keeping its cap table, ownership, and voting records completely private and isolated.

solidityERC-20Decimals = 0Cap TableTransfer Gates

How does GhostCap represent startup equity on the blockchain?

Plain English Summary

Your equity is represented as a formal ERC-20 token, but unlike speculative crypto tokens, startup shares are whole numbers (you cannot own 0.0001 shares) and cannot be traded on public exchanges. Transfers are locked by default and require unanimous founder consent or specific multisig approval.

solidityVesting EngineCliffLinear VestingClean Exits

How does the on-chain vesting engine enforce cliffs and founder departures?

Plain English Summary

Vesting ticks forward on the blockchain every single day according to your agreed terms (e.g. 1-year cliff, 4-year linear). If a co-founder leaves early, they keep whatever shares have already legitimately vested, while unvested shares are automatically revoked and returned to the company pool—eliminating oral ambiguity and dispute risks.

multisigMultisigEIP-712M-of-NQuorumGovernance

How does GhostCap’s multi-signature (Multisig) governance work?

Plain English Summary

GhostCap operates on a two-tier governance model. Day-to-day discussions and votes happen off-chain with free, gasless cryptographic signatures. Once founders reach the required consensus (e.g. 2 out of 3 approvals), the decision is submitted to the blockchain contract where multiple founder keys confirm and execute the transaction.

multisigSelf-GatingAccess ControlProtocol SafeImmutability

What stops a rogue co-founder from unilaterally altering the cap table or stealing funds?

Plain English Summary

No individual person—not even the founder who created the company—can directly mint shares, change owners, or withdraw company assets. Critical administrative functions can only be executed by the contract itself through a confirmed multisig vote.

gaslessGaslessAccount AbstractionPrivyPimlico v2Paymaster

How do gasless transactions work without needing crypto or paying fees?

Plain English Summary

Founders sign up using standard email or social login. Behind the scenes, GhostCap provisions a secure embedded wallet and sponsors all blockchain network gas fees through a certified Paymaster. You never need to purchase cryptocurrency, bridge tokens, or install browser extensions.

gaslessEIP-7702ERC-4337 v0.8Account DelegationPimlico v2

How does GhostCap combine EIP-7702 account delegation with ERC-4337 EntryPoint v0.8?

Plain English Summary

They operate together at complementary layers. Legacy ERC-4337 required deploying a separate smart contract wallet for each user, creating two confusing addresses (an EOA and a smart contract). GhostCap adopts EIP-7702 account delegation so your single Privy wallet address temporarily acquires smart contract capabilities, while leveraging ERC-4337 EntryPoint v0.8 and Pimlico for gas sponsorship and bundler relaying.

gaslessWebhook FirewallHMAC SecurityRate LimitingAnti-Griefing

How does GhostCap prevent malicious users from draining platform gas subsidies?

Plain English Summary

GhostCap runs an active security firewall webhook between the bundler and paymaster. Every sponsored request is inspected in real time: we verify cryptographic HMAC headers, restrict payload sizes, ensure the action is an authorized company operation, and verify the caller is a genuine co-founder.
