On-Chain Green Audit

€ECO is not just an ESG claim. It is a financial computer built on Solana's Token-2022 standard. Here is how the technology enforces transparency.

🍃 Transfer Hooks (Token-2022)

Unlike standard SPL tokens, €ECO uses the Token-2022 Transfer Hook extension. This means every single transfer is intercepted by a smart contract that records the transaction's carbon footprint and ensures it complies with our ESG standards. It's an automated, immutable green audit.

Anti-Greenwashing Compliance
Institutional Grade Transparency
Immutable Audit Trail

🌍 Carbon Offset Engine

A portion of the ecosystem's fees is automatically routed to the Carbon Offset Engine. This engine interacts with verified registries (like Verra) to retire carbon credits. By holding €ECO, you are directly contributing to environmental restoration.

Smart Contract Transparency

            // Simplified snippet of the Token-2022 Transfer Hook

            pub fn transfer_hook(ctx: Context<TransferHook>, amount: u64) -> ProgramResult {

                // 1. Calculate carbon footprint based on amount

                let footprint = calculate_carbon(amount);

                // 2. Record audit on-chain

                emit!(GreenAuditEvent {

                    sender: ctx.accounts.sender.key(),

                    amount: amount,

                    carbon_footprint: footprint,

                    timestamp: Clock::get()?.unix_timestamp,

                });

                // 3. Check if whitelisted (optional compliance)

                check_compliance(ctx.accounts.sender)?;

                Ok(())

            }
