Issuer: Bitlayer Foundation Report Date: May 15, 2026 Version: 1.0 Status: Public

Executive Summary

The Bitlayer Foundation publishes this Transparency Report in response to the token metrics audit conducted by Bithumb and as part of our ongoing commitment to providing accurate, verifiable information to exchange partners, token holders, and the broader community.

This report provides:

• A complete breakdown of the 1,000,000,000 BTR total supply across all allocation categories

• Detailed vesting schedules for each category, including the distinction between KOL investor and standard investor terms

• A full chronological record of all token distributions since TGE

• Cross-chain custody proof for BTR tokens bridged via Chainlink CCIP

• On-chain verification instructions and all relevant contract and wallet addresses

• Reconciliation of balance discrepancies identified during the Bithumb audit

All figures in this report are verifiable on-chain. Where applicable, on-chain addresses are provided for independent verification.

Token Overview

Token Name: BTR Total Supply: 1,000,000,000 BTR (fixed, no additional minting) TGE Date: August 27, 2025 Primary Chain: Bitlayer (Bitcoin Layer 2) Cross-Chain: Ethereum, BNB Chain (via Chainlink CCIP)

2.1 Allocation Table

Vesting Schedules

3.1 Team (120,000,000 BTR)

All 120,000,000 BTR remain in the Bitlayer team allocation wallet. No distributions have occurred and none are scheduled until August 27, 2027.

3.2 Investors & Advisor (202,500,000 BTR)

This category contains two sub-groups with distinct vesting terms.

3.2.1 Standard Investors (~150+ participants)

Note on the one-month discrepancy: The publicly communicated investor vesting schedule described a first unlock of March 27, 2026. The actual investment agreements governing standard investors specify a first unlock of February 27, 2026, one month earlier. The Foundation acknowledges that this discrepancy was not proactively communicated and is rectifying this through this report and the accompanying community announcement.

3.2.2 KOL Investors (~30 participants)

KOL investors were signed under a separate investment agreement structure reflecting their role in community building and promotional activities. Their earlier unlock schedule is a standard industry practice for KOL arrangements and was contractually established prior to TGE.

3.2.3 Why Different Terms?

KOL investors typically receive preferential vesting terms compared to standard institutional investors. The earlier cliff and shorter vesting period reflect:

1. The marketing and community-building deliverables completed at or before TGE

2. Standard market practice for KOL investment agreements

3. Contractual obligations established prior to August 27, 2025

3.3 ECO Incentive (400,000,000 BTR)

3.4 Treasury (60,000,000 BTR)

3.5 Node Incentive (77,500,000 BTR)

3.6 Public Distribution (110,000,000 BTR)

3.7 Liquidity (30,000,000 BTR)

Investor Category Deep Dive

4.1 Distribution Timeline

Total KOL distributions (Nov 2025 – Jan 2026): 259,243 BTR Total standard investor distributions to date: 8,532,580 BTR Combined investor distributions to date: 8,791,823 BTR

Cross-Chain Custody

5.1 CCIP Bridge Architecture

BTR uses Chainlink’s Cross-Chain Interoperability Protocol (CCIP) for cross-chain transfers. The mechanism is a lock-and-mint model:

• BTR locked on Bitlayer in the CCIP Lock contract is immobilized — it cannot be spent or transferred

• An equivalent amount of BTR is minted on the destination chain (Ethereum or BNB Chain)

• The total supply across all chains always equals 1,000,000,000 BTR — no additional tokens are created

5.2 Cross-Chain Supply Snapshot (as of report date)

The 0.11 BTR difference between the CCIP Lock balance and combined ETH+BSC supply is within acceptable rounding tolerance and does not represent any supply discrepancy.

5.3 ETH Investor Multisig Detail

Distribution History

6.1 Chronological Distribution Log

Period 1: KOL Vesting (November 2025 – January 2026)

Period 3: Standard Investor Vesting (March 2026)

On-Chain Verification

All figures in this report can be independently verified on-chain. Below are the relevant addresses.

7.1 Contract Addresses

7.2 Key Wallet Addresses

7.3 Verification Instructions

To verify total supply:

• Query the BTR token contract on Bitlayer: totalSupply() on 0x0e4cf4affdb72b39ea91fa726d291781cbd020bf

• Query Ethereum BTR: totalSupply() on 0x6c76de483f1752ac8473e2b4983a873991e70da7

• Query BSC BTR: totalSupply() on 0xfed13d0c40790220fbde712987079eda1ed75c51

To verify CCIP lock:

• Check balance of 0x786248b634b1ebc7b5fc809c74a1a212fc920d63 on Bitlayer

• This balance should equal ETH supply + BSC supply (within rounding)

To verify ETH multisig balance:

• Check BTR token balance of 0x87f794155148907afd333f4bf121990e2528ee39 on Ethereum

• Current balance: 60,946,366 BTR

To verify KOL and investor distributions:

• Review outgoing transactions from 0x87f794155148907afd333f4bf121990e2528ee39 on Ethereum

• November 2025 – January 2026: 259,243 BTR total (KOL vesting)

• February 27, 2026: 2,903,700 BTR (4 batch transactions, 150 recipients)

• March 27, 2026: 5,628,880 BTR (3 batch transactions, 229 recipients)

Discrepancy Reconciliation

During the Bithumb audit, discrepancies were noted between expected and observed on-chain balances. This section provides a full reconciliation.

8.1 Investors & Advisor Category

8.2 The 259,243 BTR Question

The 259,243 BTR observed moving in November 2025 – January 2026 are fully accounted for as:

• Source: ETH investor multisig (0x87f794155148907afd333f4bf121990e2528ee39)

• Recipients: ~30 KOL investors onboarded on Liquify

• Basis: KOL investment agreements — 3-month cliff from TGE (August 27, 2025), first unlock November 27, 2025

• These movements precede the standard investor first unlock and represent a different investor sub-category with contractually distinct vesting terms

8.3 Overall Supply Reconciliation

Corrective Actions

The Bitlayer Foundation acknowledges the following gaps identified during the Bithumb audit:

9.1 Gap: KOL Vesting Terms Not Proactively Disclosed

Finding: The publicly communicated investor vesting schedule did not distinguish between standard investor and KOL investor terms. The 3-month cliff and November 2025 first unlock date for KOL investors were not communicated publicly at or after TGE.

Action Taken:

• This Transparency Report (published April 15, 2026) provides full disclosure of all investor sub-category vesting terms

• Community Announcement (to be published within 5 business days) will inform all token holders of the KOL vesting schedule and historical distributions

9.2 Gap: Standard Investor First Unlock (Feb vs. March)

Finding: Public materials described the first investor unlock as March 27, 2026. Investment agreements specified February 27, 2026.

Action Taken:

• This discrepancy is fully disclosed in this report (Section 3.2.1)

• The community announcement will clarify the correct timeline

• Future tokenomics communications will reference the investment agreement dates directly

9.3 Ongoing Commitment

The Bitlayer Foundation commits to:

1. Advance disclosure: Any future changes to vesting schedules, unlock dates, or distribution amounts will be communicated publicly at least 14 days in advance

2. Monthly on-chain reports: Beginning May 2026, a monthly on-chain balance snapshot will be published

3. Exchange partner transparency: Bithumb and other exchange partners will be notified directly of any material changes to the token distribution schedule
